摘要: It is now widely accepted that the presence of a metal, primarily Pt, improves photocatalytic activity TiO2 both in liquid and gaseous state reactions. The objective this chapter to provide review on postulated mechanisms interaction Pt during reactions gas phase. literature was reviewed explore following mechanisms: (1) Schottky effect for charge separation; (2) oxygen spillover from TiO2; (3) reverse reactive intermediates Pt; (4) room temperature catalytic (5) capture zone created by (6) acidity OH groups. intention an assessment complexity between TiO2, enlist some existing unanswered questions further research.
