Abstract

Size effects in several typical photocatalysis reactions on dispersed metals and on dispersed semiconductors are reanalyzed. It is found that the reactions are characterized by a power law relation between activity and size through a typical exponent, D_R (the reaction dimension). The D_R value provides a measure of the activity-sensitivity to size and, in some cases, on the distribution of active sites. The following reactions are mentioned: hydrogenation and isomerization on binary TiO₂/Al₂O₃ catalysts, hydrogenation of methylacetylene on TiO₂, water-alcohol cleavage on Pt/TiO₂, and water cleavage on Pt/poly(vinyl alcohol).
