Abstract
Hydrogen photoproduction by a rarely studied, wide band gap semiconductor, SnO2, in powder form loaded with Pt and RuO, and sensitized by Ru(bpy):+ and organic dyes or with low band gap semiconductor. CdS. was investigated. Acriflavin, Eosin Blue, Rhodamine B, Rose Bengal and Fluorescein were used as photosensitizers in the presence of methyl viologen and with or without a sacrificial agent, EDTA. The effects of variation m concentrations of Ru(bpy):+ and MV*+ were studied. The maximum rate of hydrogen production was observed at [Ru(bpy)3 2+] = 3.75 x lo-’ mol dm-” and [MV’+] = 2.5 x IO-’ mol dm-‘. The efficiency of the sensitizers in hydi-ogen production was found to decrease in the order: Eosin Blue > Rose Bengal r Ru(bpy)?’ > rhodamme B = acriflavin > fluorescein.
