This produces ethanol and methanol if you blow co2 over it in sunshine? That sounds too good to be true, would love to see that

"Anyway, hope you enjoyed." I did, very much. I'm about to start my Honours year in an organic photonics and electronics institute, working on thin-film sensors. But I became a chemist because I wanted to be a Maker, much like you. Thank you very much, and keep up the brilliant videos.

Just phenomenal videos. Incredible free knowledge. Thank you!

I have already told all my chemist friends about your videos. I am preparing to build a gaggle of super capacitors for storage of power on my PV panels. Having a hydride storage solution would be the icing on the cake for my hydrogen powered car project...

I paid two pounds for this whole kilo. Makes sense in both weight and currency.

thanks for the recommendation. I do vaguely remember reading something about alternatives to hydrogen storage a while back. I'll dig through my old notebooks and get back to you on this one.

Current output will depend on amount of light. Voltage will depend on materials used and don't forget the electrolyte which acts as charge carrier.

As a coating on the electrode it should lower the required energy input. And yesI am planning to make a solar cell out of it with the graphene. I'll do a theory vid.

Thanks mate. I would look at sulphur doping too. Well, heteroatomic doping in general

Very Educative. Thanks alot.

If you refluxed the vapours evolved when heating the urea for graphitic carbon nitride would you get a higher yeild?

Great idea Solar FREAKIN' Roadways! combined with Graphitic Carbon Nitride in place of crystalline solar panels, I think that this is a viable solution for the future.

So basically graphitic carbon nitride doped with iron could possibly replace titanium as a catalyst in fuel cells, making fuel cells affordable. Maybe I'm wrong but that seems to be the main setback as far as creating hydrogen from the sun and using that hydrogen to fuel a vehicle. That would be very exciting if that is the case. I have been researching as much as I can into pem fuel cells and different ways to use graphitic carbon nitride. You are an inspiration.

You need to flow co2 and co over the bed as precursor materials. Beyond that I'll have to look further myself - I will get back to you on this

Wow. Had no idea H2 photocatalytic process was possible without Platinum (which I am just all out of this week). Any recommendations for safely storing the H2 for stationary power generation, such as a porous metal hydride or ammonia borane? Storage would now be my biggest hang-up as it stands. Also, do you know whether this material (undoped) could be used in the place of other traditionally Platinum catalysts - specifically fuel cells or battery vent reformers (h2+o2=>H2O)?

There are lots of ways to do that. Your best bet is to do a google search for doped graphitic carbon nitride and read the papers to see how others have done it then see what you think you could reproduce.

No sorry, no idea as of now but I am looking into it.

So at the end you could put this compund in water put it on the sun and the water will begin to split?

To be honest - I don't know. I think it is a step forward though

Very interesting video 👍

Why this process is not being adopted by the industry to produce hydrogen, instead of the traditional hydrolysis? Does it’s production still takes more energy than it releases in an hydrogen cell? Thanks for sharing your knowledge! You’re the best!

lol, mate - I have no problems with questions truly - but I haven't found the answers to your questions - I have found some answers and I am happy to share what I have found - but, I am happier when you are looking too - together we will solve these problems.

Mildly, I felt I was a bit harsh there - but researching answers is all part of the skill set required to investigate something - just asking me isn't research - nitrogen doping improves conductivity.

I know how to build a particle accelerator if that's any help

Bob, you're taking the pee ! And transforming it :) Ever thought of writing a book called something like 'Energy for Dummies" ? this is fantastic info.

I try to split the theory and practice vids as some people aren't so interested in the ins and outs of it all. Some - like you and me are. But I try to give enough info in the practical vid so it can be replicated otherwise a lot of these vids would be an hour long lol

I did read something but I'll have to look it up. Let me get back to you on that one

Lo indeed - it's photocatalytic so a sponge wouldn't really help. I know it seems unbelievable which is why the references - don't take just my word.

Could you make a vid on how to build a cell with this? Thanks. Love your videos. Keep them coming.

omg! usefull product. NICE!!!! thanks for the info sir!! nice video and nice explanation as always!

Might be able to use this actually.. few ideas. More research needed. 10 percent isnt great but isnt nothing. Notice specified by volume not weight so bit of wiggle room and design work arounds. If nothing else a coating for parts. Bet goin from dc to ac in a cell would heat enough to set it off so a cell that as the tank empties switches may make a nice buffer or backup. Not ideal but no extra heater needed. Wondering if any odd reactions i need to avoid with exotic metals, electrolytes, or containers. Hell wonder if could be infused directly on an electrolyte or a membrane. Wonder what electrical resistance or other odd properties it might have now.

Right so I need Graphene coated piece of aluminum. Paste it with g-C3N4 onto the Graphene. Then sandwich it with a piece of glass coated in Graphene. Graphene down onto the g-C3N4. Also how can you control current output of cell. Thicker electrolyte maybe? Many thanks for all your help.

Robert, will this form of Urea work from Ebay - 3LBS Nitrogen Fertilizer Urea 46-0-0 - $10.50 includes shipping. Also known as carbamide, is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO. Urea is produced commercially from two raw materials, ammonia and carbon dioxide. Large quantities of carbon dioxide are produced during the manufacture of ammonia from coal or from hydrocarbons such as natural gas and petroleum derived raw materials.

Sure - the minute i get round to it.

I should really just scroll through your channel when I'm searching for ANYTHING energy wise 😂 it happens to many more time may just pay that lil fee an see whatcha premium got lol

I think they are just trying to cash in. It's the same with all these high tech materials. It also helps to keep us out of the game unless we can make it ourselves

That's awesome! I'm still learning to make my photovoltaic solar cell lol

A quick question. Around 08:25 in the video you say to keep a cover on the urea to keep it from evaporating off. How much pressure builds up? Would a canning jar with a lid screwed down hold up to the pressure? I thoroughly enjoy watching your videos. I can't wait to see what you do next.

Lol - yeah I get quite a few offers lol. Keshe seems to be a real scam unfortunately - but I am only really repeating what I have heard and have no real experience o fthem. Some of my friends have looked into the bottle reactor and sday it is bogus - so I have left it there - have you looked into them?

I am currently trying to make g-C3N4 from Urea, however my sample always comes out darker in colour (brown-black), how can I make my outcome sample a lighter colour? I am using Furnace for the calcination process.

Lol so many questions can only be answered by doing. Basically your construction is right. Materials choice is more dictated by material properties. It will give you a voltage. You change voltage by building a few and wiring them in series or parallel depending on how you want to alter voltage in respect of ampage

That's the stuff!

3:03 you please wrote down the process please when to heat and when to rest?

It be interesting too see you make methanol an ethanol with it

How to wash graphitic carbon nitride with nitric acid

Hi Rob, Bicameral electrolysis collects H2 and O2 as two separate gas streams. Using gC3N4 as a photocatalist, I can't imagine a reaction cell geometry with two distinct gas phase collection streams. That leads me to think that only H2 is produced and H2O2(aq) concentration increases in the liquid phase. Is this correct? Did you make a subsequent video of H2 production?

Sir, can I use wax burn out furnace to decompose urea? Is it safe because the furnace is inside the lab and iam not sure the door of the furnace is air tight, and iam worried about the toxic fumes coming out of the furnace. Please help me sir..

Ok. Got that. Suck it and see. Keep going until I have the voltage and current I need. Did I get the construction correct?

Hi where might I find out more about the CO2 to methanol splitting? that sounds really neat.

Thanks for the repley, I've been looking around and its all very interesting. But the resourcesI have found (for methanol producing process) have been sadly lacking, so if you don't mind have a few questions, I haven't found answers to. is it different than a setup for H production? If so how? And could it work in ambient atmosphere? If it is what chemical compositions would it produce?

Sorry. Got it. Urea already on way from EBay. Many thanks.

Hi Rob, thank you sharing this with us. Could you please tell me if I can use any acid at the end or it must be nitric acid? Many thanks, Sorin

Dear Robert...its a good work...I am also planning to synthesize g-C3N4 from urea. However in my first attempt, I failed. I had put 0.11 gm of urea in a silica crucible covered with the lid in a muffle furnace. I increased the temperature gradually (~ 3-5 deg/min) upto 550 deg and kept it for 2 hr. But after cooling down to room temperature I found the crucible was empty as the urea decomposed totally. Can you suggest me how to overcome this problem and synthesize the C3N4 ?

@ThinkingandTinkering

9 жыл бұрын

Sayan Bayan use more urea - it's pretty chaep stuff and the energy you gave 0.11g was alot!

Is the ammonia released when decomposing urea too dangerous?? Or fatal?

3:45 I would smile at this point too ;]

Could this make it possible to produce enough H2 and 02 to run a vehicle with power from the alternator? Or are we still not there yet? Tried hydrolysis with a 1997 Geo Metro, the thing actually bogged down the motor with the electrical load... I never uploaded the videos, as this was technically a failure to produce enough gas.

Hi Robert, I like to understand the principle behind conversion of the polymer after losing its ammonia to C4N3 polymer at 550c. Is the initial polymer Cyamelide? Would really appreciate if you could add the chemical equations for the conversion to the product..

Hello, SirI got a question in terms of the hydrogen production from the Fe:C3N4.You simply said "put it in a solar cell, put it in the sun and you will get hydrogen bubbling from it".So now my question: Can you simply make a dispension of this Fe:C3N4 particles in distilled water and put it in the sun and thats all to create hydrogen?? I can't believe that the whole process is so simple, I always thought the doping process would be highl complex (hydrothermal way, ionic liquid, high temp doping etc)

Have you determined if there's a rapid yield of hydrogen from the photocatalytic process after doping the graphitic carbon nitride with iron? I'd really like to see a video of this stuff in action. I guess I'll have to try to make some of this and do my own experiments, I want to find out if the intensity of light increases the rate of the reaction, and just how hot this stuff can get before it starts breaking down, and whether it will work with steam, or better yet, supercritical water.
