Abstract
The bandgap of CdS increases with decreasing coverage when CdS is supported on silica (see plot of Ebg against CdS concentration c). Likewise the photocatalytic activity of these heterogeneous photocatalysts increases, as illustrated by the relative rate (vrel) of an organic addition reaction. CdS (A, vrel=1), CdS-50/SiO2 (B), CdS-30/SiO2 (C), and CdS-12/SiO2 (D).Keywords
