Photocatalysis: Principles and Applications

Photocatalysis is the acceleration of a photoreaction in the presence of a catalyst. Light is absorbed by an adsorbed substance in catalyzed photolysis. However, in photogenerated catalysis, the photocatalytic activity is based on the ability of the catalyst to generate electron-hole pairs which create free radicals. Homogeneous photocatalysis and heterogeneous photocatalysis are the two primary categories of photocatalysis. In homogeneous photocatalysis, the photocatalysts and the reactant...
