Photocatalysis - Wikipedia

In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst.In catalysed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity (PCA) depends on the ability of the catalyst to create electron–hole pairs, which generate free radicals (e.g. hydroxyl radicals: •OH) able to undergo secondary reactions.
