摘要: Abstract The effects of Au particles different sizes were investigated on the photocatalytic decompositions methanol and ethanol pure or N-doped TiO 2 . IR studies revealed that deposition promoted dissociation both compounds during illumination also resulted in formation formate species. Whereas photo-induced occurred to only a limited extent , Au, particularly as nanosized particles, markedly enhanced rate photocatalyzed reactions. An interesting feature photodecomposition was that, besides H CO CO, significant amount methyl produced. Addition O alcohol cases decreased level formed, case completely eliminated. with lower bandgap catalyzed photodecompositions even visible light.
