Sustainable hydrogen made possible with a new catalyst

This video shows gas bubbles being produced by water electrolysis using a new mixed cobalt manganese electrocatalyst. Unlike current standard methods, this catalyst is not made from rare-earth metals, making it a more sustainable option.

The press release can be seen here:

It's been two years now. Why isn't this saving the world already?

[hardwareful]

Awesome!
"Eventually, the team overcame these issues by trial and error, and discovered an active and stable catalyst by inserting manganese into the spinel lattice of Co3O4, producing the mixed cobalt manganese oxide Co2MnO4."

I just love the detailed explanation, I didn't know that baking soda could do that...

The nice thing about Platinum group metals is that they are recyclable and lose little of their value in doing so. There is a pretty stiff initial investment, but it is returned on recycling.

Despite how amazing it looks, burning that hydrogen with oxygen never create as much energy as the input

[chriscorbin]

Stanley Myer pumped hydrogen directly into his gasoline engine. He used distilled water . That was in the mid 1990's no need to carry tanks of hydrogen. He made it while driving down the road. Unfortunately he died or was poisoned.

The catalyst is likely made of a solution of Mn(NO3)2 and Co(NO3)2 in a specific ratio saturated dissolved in water then diluted to 4-8 times its volume in a carrier like methanol/ethanol. and baked at 410C in several layers.

Catalyst only lower the activation energy but have no impact on the energy needed to electrolise water. This may increase the efficiency of producing hydrogen from below 80% but does nothing for the high costs of storage and transport or the low efficiency and high cost of fuel cells.

What voltage(s) were you applying to obtain this reaction - specifically the 1 Amp reaction

[CatboyChemicalSociety]

assuming this is the anode because its the oxide what is the oxygen evolution potential of this mixture because it should atleast be comparable or lower than industry standard 1.3V for Ir-Ta.

[networkedperson]

if only youtube would allow uploading videos longer than 41 seconds...

[johnslugger]

*This is Platinum Chloride mixed with 50/50 Graphite and Activated charcoal powder and then baked at 1200C. to activate. PtC*

[MarissaAva-jcze]

Can someone explain to me the experiment is in full detail

[victoryfirst]

What exactly is this new catalyst Sir ?? Thanks

I am curious about whether it will at some point be possible to create a hydrogen on demand combustion vehicle? Ie just enough hydrogen would be produced at any passing moment to be injected and combusted inside an adapted engine so that it would not have to be stored. I think the main argument against hydrogen combustion is that hydrogen needs to be stored in compressed tanks. What if it didn’t? What if you completely bypass storage and have the catalyst progressively only making enough gas to drive each piston at that given second in time and then keep creating more for each explosion as time goes on. Will this ever be possible? Obviously there would still have to be an electrical component to split water but if the demonstration in this video is accurate it appears that it may very well be possible and also efficient enough to replace petroleum and battery only vehicles? I’m not saying it is possible yet but could it theoretically be done?

[damiensadventure]

Isn't something like this in Fiji water right now during the recall?

[mohammadhashemi]

what is the voltage ised in this experiment and who is making that catalyst?

[amiraryin]

Hiii, Can I buy the exact method of making this electrocatalyst from you?

One of the most pressing issues we face today is finding a renewable and environmentally friendly solution to transport and logistics.

Hydrogen holds immense promise as a potential solution to this problem.

Hydrogen can be used to power Hydrogen fuel cell cars or can be used in certain types of ICE such as a liquid piston engine.

If Hydrogen could be produced rapidly end efficiently using a catalyst then it's possible that one day cars could generate their own hydrogen to use as fuel. The fuel tank could contain a catalyst and would only need to be filled with water.

If the catalyst makes the process efficient enough it doesn't matter if it requires electricity.

The hydrogen could then be used as fuel for a liquid piston rotary engine (these engines work well with hydrogen), and the only emissions would be steam.

If this is possible then I hope this is the direction green automotive technology goes in the future. Cars would handle very similarly as they'd still be using an ICE, but running costs would be so much cheaper and it'd be good for the environment.

it would reduce the cost of living a lot. it would practically eliminate fuel costs, and because it would make the transport of goods so much cheaper, logistics networks costs would be massively reduced which would cause the price of goods to come down a lot.

Yea but it needs to be extracted from water, not hydrocarbon compounds.
