Rice University reactor produces pure hydrogen peroxide solutions from water, air and electricity

The production of hydrogen peroxide can be much safer and simpler through a process developed at Rice University.

A reactor developed by Haotian Wang and his colleagues at Rice’s Brown School of Engineering requires only air, water and electricity to make the valuable chemical in the desired concentration and high purity.

Their electrosynthesis process, detailed in Science, uses an oxidized carbon nanoparticle-based catalyst and could enable point-of-use production of pure hydrogen peroxide solutions, eliminating the need to transport the concentrated chemical, which is hazardous.

By using a solid electrolyte instead of traditional liquid electrolyte, it also eliminates the need for product separation or purification used in current processes, so no contaminating ions will be involved.

“If we have electricity from a solar panel, we can literally get hydrogen peroxide from just sunlight, air and water,” said Wang. “We don’t need to involve organics or fossil fuel consumption. Hydrogen peroxide synthesis by traditional, huge chemical engineering plants generates organic wastes, consumes fossil fuels and emits carbon dioxide. What we’re doing is green synthesis.”

Hydrogen peroxide is widely used as an antiseptic, a detergent, in cosmetics, as a bleaching agent and in water purification, among many other applications. The compound is produced in industrial concentrations of up to 60% solution with water, but in many common uses, the solution is far more diluted.

Too much talk, why dont you show how the cell works?

A paper from 2016 uses a catalyst made of the rarest elements on earth: gold, palladium, and the not-rare titanium dioxide.

🤔is this a meme

Okay but how does it work are they just shocking the water and putting oxygen into it you didn't describe how it works at all

[فريدالقباطي-وغ]

What's catalyst that use for reduction oxygen to produce hydrogen peroxide

[Probc-oryu]

is this 100% H2O2? the water used is it ultrapure water or just normal deionised water? Is there a test to look for impurities in the H2O2 such as sodium and other minerals, and is the H2O2 that you produced stable?

[panjobasbaraparimo]

File the academical papers of the complete process. Method, Construction, Yield.

Just showing it is chinglish IMO

[Preyhawk]

Where can i buy this catalyst or how do i make it at home?

[anilkumarsharma]

Passing current through water💧💦 produced hydrogen peroxide???

[Not_SatoruGojo]

Do you research rice in your university?

[BushLieWorldDie]

Still waiting to buy the anod katods. .

[は私です彼の名前]

So when is this coming to market. I am sick of so many plastic bottles. I have 6 pets and go through peroxide like crazy!!

[FunFunFunFun]

But what can we do to get this technology?

[pfc]

Wow... a hydrogen peroxide solution that’s so a strong oxidiser that it can reduce permanganate!

[AndyU]

'pure'...

'solution'...

[anilkumarsharma]

Mixing air in water💦💧??? Or oxygen and water💧💦 in vaccum chamber??

[BushLieWorldDie]

So where can i buy them and when? And whats the consumtion of electricity amount per cl?

[gregrarata]

Sorry, but 1% by weight hydrogen peroxide as a raw product is far to low concentration to be considered industrially useful... therefore I believe that anthraquinone process (the traditional method for production of hydrogen peroxide ) will stay with us for a quite long time... especially that it is well established mass scale industrial production (millions of tones per year globally)...

[WOLFNBEAST]

Can the process be reversed to use peroxide to generate electricity

[kashifabbasiabbasi]

What apparatus costs to produce hydrogen peroxide(50%) by converting alternating current to direct current through water in the presence of catalyst what?? Please explain
