A little more technical information in today's S&V article: https://www.science-et-vie.com/article/ ... ropre-8778

(...)
For this, they developed a stack consisting of two chambers separated by a membrane. In the first, an anode coated with titanium dioxide (TiO2) produces electrons under the effect of light, as in photovoltaic cells. This triggers the degradation of the polluting gases around the electrode and creates protons (H +).

Protons and electrons pass through the membrane and end up in the second chamber, near a lead cathode, which couples them to produce dihydrogen (H2). This one can be stored and used later as fuel, for cars in particular.

Treat the methanol vapors

At present, this system does not treat all pollutants. "We concentrated on methanol vapors. We have also demonstrated the concept with ethanol and acetic acid. We are now extending it to methane and acetaldehyde, "says Sammy Verbruggen of the University of Antwerp.

This stack is still only experimental, and the team still needs to improve its efficiency. But Sammy Verbrugge already dreams of its applications: "I would like to try it in the chimneys of the paint manufacturing plants, where the vapors are heavily loaded with organic solvents."


It is therefore in fact "industrial" pollutants ... and we now know where the H2 comes from ... ultimately much less miraculous than the first announcements (uh, methanol is already a fuel, eh ... )

I assume they are the same people:

Not stupid as an idea .... You recover at the exit of your decathlon mask your expired CO² and your water ... You pass that in your catalyst that you have in your backpack ... And in the evening you have the ethanol for the aperitif ...

Health hips !!!

The only thing safe in the future. It is that there may chance that it conforms to our expectations ...

You still need a solar panel on the backpack anyway .... But it's well worth it.

Highly industrialization!

(...) The nanochimiste Adam Rondinone and his colleagues at Oak Ridge Laboratory, the US Department of Energy, have found a method of transforming the CO2 fuel ethanol - and all this by chance.

"We were in that study the first step of the reaction when we noticed that the catalyst realized throughout the reaction itself," says Rondinone.

The researcher describes the ingredients of his experiment as follows: we take a pinch of copper nanoparticles which we sprinkle on a surface of carbon particles enriched with nitrogen. The carbon particles form “nanospikes”, that is to say tiny lightning rods, only a few atoms wide at their top, and capable of creating a strong electrical voltage field (one nanometer = one billionth of a meter).
(...)

This very reactive mixture produced in a small space becomes a catalyst which, under the effect of an electric current, directly converts ethanol in carbon dioxide.

According to the researchers, the effectiveness of the process is to 63 70 percent, and therefore produces little waste. Moreover, it is energy efficient, because a voltage volt 1,2 just enough to start the reaction.

(...)

Thanks to the relative simplicity of the device (cheap materials, low power consumption, ethanol production at room temperature), Rondinone and his colleagues still believe in an industrial application of their process. For example, it could store the surplus energy produced by solar panels or wind turbines turning it into ethanol. "This could help smooth out irregularities in renewable energy production. "




" capable of creating a strong electrical voltage field "

Come on... why go any further if you have just discovered an INFINITE Electricity Battery?!
