Abstract:
Hydrogen is considered to be the ideal fuel for the future because it can be obtained from renewable energy, its life cycle is clean and renewable. The sun and the wind are two major renewalbe energy sources with promising applications in hydrogen generation. In present, the renewable energy is used for only 5% from the first hydrogen production (from the water electrolysis) and the rest 95% is obtained from fossil fuels. Hydrogen generation from renewable energies is not a popular method because the high costs, but even so, the photovoltaic electrolysis of water may be a competitive method, making the costs go lower by using new technologies. An viable alternative for hydrogen generation is the use of TiO2 for the water photocatalityc decomposition. These study investigates the newest approach and the future directions in hydrogen photocatalytic production using TiO2. So it will have a retrospect of water/air photocatalytic purification and also other photocatalyts besides TiO2.
