Dear Artur Braun, this is not a consultant service, it is only a question I have in my mind and want to know more about it.
I know that the main methods for Hydrogen production by water splitting are: thermochemical, photobiological, and photocatalytic.
I also know that some materials frequently used are: ZnO, TiO2 and cobalt ferrites.
What I need to know is if there are more methods, materials and the experimental conditions used in order to avoid the CO2 generation and a high energy consumption during hydrogen production.
Hope you can help me.
Thanks in advance, Pedro Villegas.
Dear friend thanks for your prompt response.
Yes, I google it and I found what I previously commented to you.
Can you provide me more details about the specific materials you use in Photoelectochemical method?
Thanks again, Pedro Villegas
Thanks again,
Can you explain me please what are GaAs and CIGS?
What about the experimental conditions?
Regards, Pedro Villegas
GaAs is Gallium Arsenide, CIGS is Copper Indium Gallium Sulfide. All this is a current subject to scientific investigation, so it's difficult to give a short overview within a simple researchgate discussion...
Thank you so much to all the answers, have a beautiful day, Pedro Villegas.
Dear Artur, gasification of coal (char or even biomass) in version POX is the simplest version: C + H2O + 1/2O2 = H2 + CO2
Best regards
Hi Pedro,
Photoelectrochemical cells are devices that produce hydrogen in a process similar to the electrolysis of water. However, this type of cells electrolyzes water to hydrogen and oxygen gas by irradiating the anode with sunlight. The main component of the PEC cell is the semiconductor, which converts incident photons to electron–hole pairs. These electrons and holes are spatially separated from each other due to the presence of an electric field inside the semiconductor. The photogenerated electrons are swept toward the conducting back contact and are transported to the metal counter-electrode via an external wire. At the metal, the electrons reduce water to form hydrogen gas.
Recently, we have been working on the fabrication of various photoelectrodes for these systems. If you like to see more you can search the following articles.
All the best.
