Abstract:
The growth of industrialization, which is forced to use non-renewable energy sources, leads
to an increase in environmental pollution. Therefore, it is necessary not only to reduce the use of
fossil fuels to meet energy needs but also to replace it with cleaner fuels. Production of hydrogen
by splitting water is considered one of the most promising ways to use solar energy. TiO2 is an
amphoteric oxide that occurs naturally in several modifications. This review summarizes recent
advances of doped TiO2-based photocatalysts used in hydrogen production and the degradation of
organic pollutants in water. An intense scientific and practical interest in these processes is aroused
by the fact that they aim to solve global problems of energy conservation and ecology
