Mechanistic Principles of Photocatalytic Reaction

  • Chapter
  • First Online:
Heterogeneous Photocatalysis Using Inorganic Semiconductor Solids

Abstract

As developments in semiconductor photocatalysis flourish, profound success is being recorded in the elucidation of reactivity vis-à-vis mechanism. The mechanism of photocatalytic reactions lies between two limits. From viewpoint of photochemical kinetics, the reaction mechanism will be controlled by the properties of light and consequences of light absorption. However as mass transfer dominates, the process will be controlled by the non-catalytic diffusion mechanism. This chapter highlights both diffusion and photocatalytically controlled kinetics in semiconductor-based heterogeneous regimes. In the final place, some conventional analytical methods for validation of photocatalytic reaction mechanism are discussed.
