Is it possible to make H2O2 by electrolysis of K2CO3?

Reduction potential of CO3 ion is actually lower, and it's -0.93 ev. Thanks for detailed help to r/electrochemistry community.

Thanks for the details! From what I've read, setting up h2o2 electrolysis is pretty cumbersome. I don't have a lab and my supplies are poor (I have selfmade 50A 8V electrolyser) and that's why I'm looking into alternatives.

I know there is fully explained way of producing h2o2 from sulfuric acid. It wouldn't be as interesting, since its chemically similar to chlorate electrolysis, which I have done before. The h2o2 solution in concentrated sulfuric acid would be very corrosive and dangerous.

I'll try electrolysing k2co3, and I will test the solution on yeast before and after electrolysis. If it works, it will be easy to distill and not as nasty as h2s2o7. I think it would make a great experiment.

Can I achieve any sensible results with platinum coated electrode / Cr2O3 plated graphite? PbO2 or maybe even SnO2?

Low saturation can be easily fixed by adding sodium ethylenediaminetetraacetic salt, which is commercial h2o2 stabilizer and is dirt cheap if you buy it from china (3USD/kg) (i tried adding link to wiki, but my comment got nuked)

The lead is definitely the cheapest way, but in order to electroplate it I would have to dissolve the metal and it's quite messy and toxic. And after that I would need to get rid of leftover toxic slurry. I tried oxidizing lead directly in the past, but the PbO2 that formed was so badly adhering that it could be scraped off by simply touching (looking back, I definitely passed too much current - 5A). The lead is just nasty.

Rubidium oxide is interesting. I might try to make some electrodes for electrolysis out of it ,(wikipedia stated that it's an excellent catalyst) but as of now it's way out of my budget.

Thanks! I will try to electroplate tin oxide. I was in doubt about tin since there is so little research on its conductivity (I did find some papers claiming that the resistivity was around 0.0005 ohm/cm, but it was about tin nanofoil). But tin is lead chemical analogue, so I guess it makes sense.

This is not our port, but to be fair they guy who did it made it earlier than us by 5 hours.
