- 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.
A paper from 2016 uses a catalyst made of the rarest elements on earth: gold, palladium, and the not-rare titanium dioxide.
It implies that titanium dioxide can be substituted being cost effective for palladium, gold..is it as effective as other rarest elements
H202 the sequel to water!!!!
So where can i buy them and when? And whats the consumtion of electricity amount per cl?
Too much talk, why dont you show how the cell works?
He put all of his skill points in chemistry and none in video production
Great work! Very cool
But what can we do to get this technology?
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
Mixing air in water💦💧??? Or oxygen and water💧💦 in vaccum chamber??
Wow... a hydrogen peroxide solution that’s so a strong oxidiser that it can reduce permanganate!
..... ... ... sarcasm I hope? permanganate can be reduced by nearly anything..peroxide is the reducing agent here.. you basically said hydrogen peroxide is such a strong oxidizer that it can't oxidize permanganate and reduces instead.
Like Thetodor said... Permanganate is the oxidizing agent and gets reduced (Mn 7+ to Mn 4+). Peroxide here is the reducing agent and gets oxidized (O to O 2-). This also happens with diluted H2O2.
Appreciate Video! Sorry for chiming in, I would appreciate your initial thoughts. Have you heard about - Peyvery Phrenic Prevalence (do a google search)? It is a great exclusive guide for get your original hair color back and look young minus the normal expense. Ive heard some awesome things about it and my buddy at last got excellent success with it.
@@ramreshly4734 nice scam
What's catalyst that use for reduction oxygen to produce hydrogen peroxide
cathode can be anything but the important thing is the special anode running at 500ma/cm^2 which causes OH* radicals to be attracted to the anode but with flow in the central compartment of an electrodialysis cell setup you are able to obtain H2O2 as this intermediate is caught up in the flow and gets pushed out of the setup instead of forming ozone at the anode.
I will make a video of the special anode soon since I found someone who might hook me up with one.
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?
it isn't, otherwise the h2o2 would destroy the hoses used
I'm curious on the percentage also but it's probably distilled water idk
@@arturpinheiro5518 that seems unlikely. I routinely have 35% HP in sprayer hoses and in contact with plastic for years and years with zero issues. I am no expert but.....
@@coppulor6500 higher concentration is wired it can explode and do reactions unlike 35%
Dumb question. 100% H2O2 is known to decompose with extreme violence in contact with most contaminants.
Passing current through water💧💦 produced hydrogen peroxide???
我是李焕，我学会了，谢谢老师
Now stores run out of h2o2 due to the coronavirus, how can you help with your system?

So no palladium catalyst required?
Nobody said that! ;)
it uses platinum electrode so you still need a catalyst!!

🤔is this a meme
No it's not a meme. Your psyche jumps immediately towards making a racist joke. Think about how they felt when they read your comment maybe okay with it but what if you hurt their soul what if. What if you hurt them , what if.... come on man yeah it's funny but is it necessary why cant you spread LOVE instead of hurtful jokes funny for some but not for all. We need more compassion let's go human be a better human

Can the process be reversed to use peroxide to generate electricity
no
Do you research rice in your university?
I think so. As an example I have encountered countless people graduated from Clown university, and as a matter of fact they actively embody the subject of clowns.
Where can i buy this catalyst or how do i make it at home?

@@maib1089 Hi he is making ozone with high voltage spark and then making it react to water
@@AnujSingh-lq8ty what is the role of catalyst in this reactions. can we irradiate water directly with UV-C to form H2O2 ?
@@maib1089 Hi I am sorry I have very little idea about chemistry, I am also looking for H2o2 generation method, if you have any idea kindly share
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
BDD electrodes and in the future I will show a video of something similar.
In this process, caction ions positive one move towards cathode of steel terminal,, anions negative move towards anode terminal of graphite.. carbon... how much dc current amperes consumed in this process.. moreover, oxygen produced can be compressed to liquid oxygen used in hospitals..Pl elaborate
@@kashifabbasiabbasi5388 700ma/cm^2 andd you need an ED cell setup with 2 ion exchange membranes where the central chamber containing all the neutral stuff like hydroxy radicals that form due to the insane current density.
the anode chamber is full of H2SO4 and cathode chamber is NaOH or pure water.
The central chamber is hooked up to a peristatic pump to pump out hydroxy radical containing water which will recombine into H2O2.
The oxygen byproduct in this process is not usable for it contains mostly OZONE and cannot be used in hospitals.
Can you produce gunk from electriciyy?
what
大学网站查不到你们的信息？？
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!!
What are you doing with your pets? What kind of pets?
Yes, I, also as an owner of several pets, have these questions.
@@MatCran i think he bleach them so the have platin blonde fur :D
You need to develop solar cells impervious to solar flares
Please explain the difference in the process(if any) of using deuterium and hydrogen dioxide to make hydrogen peroxide.
What the literal f are you talking, it makes absolutely no sense
@@GreenCaulerpa I am asking if it matters if Protium or Deuterium are used to make Hydrogen Dioxide and Hydrogen Preoxide. I know the difference, I want to see if someone else knows.
@@GreenCaulerpa of course it makes sense, you just don't know what he's talking about
@@tasbirmiah5247 Lol, no it really doesn‘t as it‘s clearly shown by the „hydrogen dioxide“ part....
I‘m a chemistry student after all so I better should be able to tell
"Hydrogen dioxide" XD dude just say water. Also there is a slight difference when using deuterium and normal hydrogen such as slower rates of reaction etc.
Hory cow!! it is nice video.
Using rice to make water
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)...
Not really, at 1% it's already 3X too concentrated for use as a fungicide in contact with live plant matter. 1% HAS its uses, and even concentrations of 0.25% are extremely useful.
'pure'...
'solution'...
Wowww!! no $$#$^
*NO HELP HERE!!*
Rice University is an international university, for those who are worried about seeing the Chinese.
No one was worried but your dumbass comment worries me
question this hydrogen peroxide food grade for everyday use for people to ingest . It should be a study how works on a human body a it's Benefits. Doctors say it not good to drink for an very day use . We'll use it very day in my water 6-10 drops, and feel great I have improved my health in many ways.
Please don't drink hydrogen peroxide because it will harm you
Judging from your articulation it seems as if you were having a stroke. Maybe due to hydrogen peroxide ingestion?! Don’t drink it, really!
Became a Chinese University?
Don’t envy him! Yes, he is a Chinese, and Rice U values his talent!
You know it's a Chinese university when it called RICE
It's too.bad it's jest water
Worth having now!
