Light-induced hydrogen formation and photo-uptake of oxygen in colloidal suspensions of α-Fe2O3

Abstract

Hydrogen evolution and oxygen reduction as a function of pH of the electrolyte have been investigated for α-Fe2O3 powders and colloids by means of a solar simulator. The discrete particle dimensions and surface dynamics of iron oxide seem to be the dominant factors leading to H2 generation despite the unfavourable position of the conduction band in Fe2O3. Evidence is presented that photo-uptake of O2 occurs in α-Fe2O3 suspensions.
