Photocatalysis

The acceleration of a photoreaction in the presence of a catalyst is referred to as photocatalysis. Light is absorbed by an adsorption substrate in photolysis catalysed by a catalyst. The ability of the catalyst to make electron–hole pairs, which generate free radicals (e.g., hydroxyl radicals: •OH) capable of secondary reactions, determines the photocatalytic activity (PCA) in photogenerated catalysis.

Water splitting through photocatalysis is a sustainable pathway for hydrogen generation. In our group we are presently focusing on the development of several photo active catalysts which can favor hydrogen generation while consuming lowest energy. The target is to develop photoactive materials to serve the commercial purposes.
