Origin of the Activity of Semiconductor Photocatalysts

Abstract

The properties that affect the photoactivity of semiconductor photocat- alyst are pervasive and the interplay of variables in the semiconductor-assisted photoprocesses is complex. Understanding the heterogeneous, advanced oxidation photoprocess is crucial to its harvest, and must therefore be emphasized. This chap- ter is devoted to the highlight of critical properties necessary for the realisation of efficient photocatalytic process, cutting across surface science, solid state synthesis and process operation.
