Abstract
A photocatalyst is a semiconducting substance which can be chemically activated by light radiation that results in oxidation-reduction (redox) reaction, i.e., it has a photocatalysis action or photoactivity. As illustrated in Fig. 1.1 [16, p. 147; 24, p. 10], photocatalysis is similar to the photosynthesis in plants in the mechanism, in which chlorophyl acts as a catalyst to produce oxygen from carbon dioxide and water. Chlorophyl is a very powerful photocatalyst. The photocatalyst in the photocatalysis process corresponds to the chlorophyl in the photosynthesis process.
