Photoelectrochemical processes use specialized semiconductors to individual water into hydrogen and oxygen. Solar thermochemical hydrogen generation works by using concentrated solar energy to travel water splitting reactions typically alongside with other species for example metal oxides. This can be a consequence in the lowering temperature, as shown in Determine 3c. https://hectoravlhs.blogsidea.com/32394204/the-best-side-of-save-fuel-with-water
