Interfacial Charge Transfer Reactions in Colloidal Dispersions and Their Application to Water Cleavage by Visible Light

  • Michael Grätzel

Abstract

There is ample evidence from present day analysis1 that conventional energy supplies are insufficient to cover future energy needs and, in fact, need to be supplemented by alternative resources, such as solar radiation. Therefore, during the coming decades mankind is faced with the challenging task of conceiving devices that accomplish the conversion and storage of solar energy. Endeavors have to be undertaken now to provide a broad scientific basis for such a future development. Devices that harness visible light and convert it into a storable fuel have to be designed and thoroughly investigated. One process that deserves particular attention is the cleavage of water into hydrogen and oxygen by visible light.
