Photochemistry

Definition

Photochemistry is the study of chemical processes that occur because of the absorption of light. The study of photochemical systems that use sunlight to drive important chemical reactions or to generate electricity is of great practical significance for the development of sustainable sources of energy.

    Photocatalytic water splitting is a route to clean H2, but approaches based on hybrid semiconductor–metal nanoparticles often rely on sacrificial reagents to complete the oxidation half of the overall reaction. New research uses CdS nanocrystals modified with metallic and molecular co-catalysts to simultaneously produce H2 and O2 from water using visible light.
