Significant Effects of Anion in Aqueous Reactant Solution on Photocatalytic O2 Evolution and Fe(III) Reduction
The apparent quantum yield at 365 nm over TiO 2 photocatalyst for O 2 evolution and Fe 3+ reduction in an aqueous FeCl 3 -HCl solution was 51%, and more than 15 times higher than in an aqueous Fe 2 (SO 4 ) 3 -H 2 SO 4 solution.
