Hydrogen Production by Photocatalytic Water Splitting

Hydrogen, unlike fossil fuels, bums without emitting environmental contaminants. Hydrogen is believed to be one of the possible energy carriers of the future, because it can have a significant function in reducing the current environmental pollution produced by fossil fuels [37,137], 

Water splitting by electrolysis is an oxidation-reduction process where the oxidation reaction occurs at the anode and the reduction reaction at the cathode (see Section 2.3.3).
