As per the paper, your 3 chambered experiment required O2 on both electrodes. The porous carbon with O2 diffusion is on both sides. Note, also, that the 3 chamber diagram displays the expected reaction on chamber 1 and chamber 3 of which both show O2, which is supplied via the porous carbon. You omitted this in your experiment. Recheck the paper.

Did you test the stability of H2O2 towards your garden clay pots? I imagine that clay from clay pots contains a big deal of metallic oxydes like Fe2O3 (I say this from the colour). Normally H2O2 or superoxyde anion (HO2(-)) is sensitive to metals like iron. H2O2 is not so sensitive to NaOH as you think. I have worked in a shampoo and hair products factory... we worked with H2O2 (30%) that was dilluted and incorporated into a wax stiffener to make a 10% peroxide cream for professionals... to discolour hairs prior to (re)dye process. Such thick cream was a nightmare if catalytic decomposition of H2O2 ever occured... because the cream would expand like a solid foam... H2O2 30% is 100 volumes so 10% is like 33 volumes... imagine your 10 cubic meter batch that goes 330 cubic meters... not pleasant to see nor to manage. Also sealing caps can't be airthight because of the risk of explosion of the bottles, the use of flipping caps was prohibed because of the risk of splashing to the eyes in the case of an internal overpressure. During the stability testings for long term storage we used various products acids, bases, organics, minerals... and submitted our samples to heat, to UV and determined the volume expension during time. Base was as good as H2SO4 what is often used. One of the best stabilisator was sodium stannate (a product that is quite basic). Maybe the use of Na2CO3 (quite basic) and a bit of Na2SiO4 would help generate sodium percarbonate (2Na2CO3.3H2O2). This paper explains the preparation of percarbonates from carbonates... but they use platinum (maybe MMO electrode will work?) krc.cecri.res.in/ro_2000/111-2000.pdf This one too is about percarbonate via electrolysis. www.researchgate.net/publication/244671808_Simultaneous_Anodic_and_Cathodic_Production_of_Sodium_Percarbonate_in_Aqueous_Solution This one starts from CO2 www.freepatentsonline.com/7094329.pdf Percarbonate is a good source of H2O2...upon acidification it sets H2O2 free (of course one must use an acid that doesn't react with the H2O2 ... HCl, HBr or HI are excluded). PHZ (PHILOU Zrealone)

Well at least you tried it and that is what counts right ? Thank you for taking your time to test it. You are great :)

In industry, the electrolysis of concentrated sulfuric acid is used to produce hydrogen peroxide, and the processes going at the electrodes are quite complex. And the huge problem of home-achieving peroxide is that any heavy metal or protein contamination will destroy the peroxide back into water and oxygen. You should also know that not the current itself you need to control but current density! I.e. current divided by electrode surface area. And this is true for any alectrochemical process. I can try (if you need) to find one old soviet book describing production electrochemistry technologhies of several substances.

I think if you put water under extremely high pressure, freeze it, I mean like ice 7 pressures so the ice doesn't expand, THEN you can do this. Should be water behaves as a polymer at some pressure, and that corresponds to h2o2's physical appearance at 100%, a really thin polymer

I would expect that one serious problem would be that either the electrodes(depending on what you use) or any corrosion from your wiring can both decompose hydrogen peroxide almost as soon as it's made. There's also the problem that a significant percentage of chemistry patents just don't work.

that's right and maybe there can be traces of Manganese dioxide in there too, what destroys all H2O2 immediately.

didn't the paper show 02 not normal air in the cathode? i would be curious to see the results of the same experiment but bubbling oxygen instead.

According to Wiki, simply burning sodium metal in excess oxygen yields primarily sodium peroxide, which can then be dissolved in water to give hydrogen peroxide and sodium hydroxide. A better idea might be to dissolve it in something like phosphoric acid, ultimately shooting for a reasonably stable, neutral, and buffered product which should be possible to distill if desired. Burning potassium in oxygen is supposed to generate the superoxide, which also yields peroxide upon hydrolysis while evolving O2 gas. I wonder if it might be possible to get H2O2 by burning H2 in ozone or if anyone has tried that.. I'm not sure if that even makes sense; it just popped into my head while writing this... I've always found it kind of strange that a chemical that's in some sense "made of" air and water should a) need so many other reagents to prepare, and b) be so harmful to human health given how great air and water are for staying alive. If only it were possible to chug a pint of the stuff and then spend the next hour or so having fun under the sea.

Missing pure O2 in a gaseous state to oxidate the H2O. H2O + O2 (electricity) -> H2O2

Feeding the cathode with pure oxygen would definitely help the rate of the process (by up to a factor of 3 possibly), but I still think the simple graphite electrode just doesn't have the catalytic activity needed for oxygen reduction. Honestly, there are so many factors in this experiment, that it's very difficult to tell what could be changed to make it work (other than copying the original paper perfectly).

26:48 try 1% real peroxide with same amount of H2so4 and naoh mixture to test if it also gives same yellow colour or not !!

the issue is that hydrogen peroxide is unstable and will just nucleate at the porous pot walls. you are better off making a 3 compartment cell casting gelatin membrane walls for it impregnated with sodium sulfate mixed into the gelatin. dont use gel bridges as the area and thickness of the membrane is what affects the rate of flow of ions through it. usage of other polymers might be nice like did you try silly putty PVAglue + borax with a scaffold as a membrane preferably some type of plastic mesh. doesnt work for sulfuric acid but might work for peroxide.

@@ScrapScience Mr. Scrap Science, I picked up the excellent reference book, "Industrial Chemicals", 4th edition (1975). The chapter on Hydrogen Peroxide mentions three ways of making H2O2. Two of those ways involves a precious-metals catalyst, BUT, the third way does NOT require a catalyst! It's called the Shell Process. *In this process, 02 oxygen & 2-Propanol are placed inside of a reaction vessel, and the O2, strips the Hydrogen from the 2-propanol, yielding Acetone & H2O2!! I'm in love. Yield is 87% based on conversion of the Alcohol! NO catalyst needed!!* The only catch is the vessel has to be made of Aluminum (or glass, or enamel, or any other material that won't react with H2O2). I think Aluminum would be a great choice. The only other thing is moderate pressures & temp. Temp of 100C to 140C is not a big deal, since Aluminum pressure cookers obviously deal with higher-than-boiling temps. Pressures are only ~16 Atmospheres (which isn't high at all compared to Urea, requiring 2500 to 3000 PSI). If you decide to build a reaction vessel, I think you can just put the Aluminum "tank" inside of a larger "steel" vessel, in which the space between the Aluminum vessel and the steel vessel is filled with a solid concrete-like thermal insulator. I think it's very doable. A pressure vessel is something you build only once in your life, then you've got H2O2 for all eternity, and NO catalyst needed! *Please Let me know if you want me to video record that page of my book for you.* ... Btw, you may also want to look at Ullmann's encyclopedia of industrial chemistry, they have an entire chapter on H2O2, including the Shell Process (I've got it in PDF, it lacks details as it points heavily to other references, including old patents).

I notice it says at 27:20 current density of 394A/m^2 which is equal to 39.4 ma/cm^2 which means so if your electrode was 1cm^2 then 40ma is ok however it looks like more.
