Abstract
Abstract Ag 3 PO 4 nanoparticle of ~ 100 nm size was synthesized by an ion-exchange reaction between AgNO 3 and Na 3 PO 4 at ambient condition. The dark yellowish Ag 3 PO 4 with a bandgap of 2.44 eV revealed significant visible-light absorption. Novel heterojunction structures of Ag 3 PO 4 /TiO 2 were then fabricated by covering the surface of Ag 3 PO 4 with polycrystalline TiO 2 by sol–gel process. Under visible-light irradiation (λ ≥ 420 nm), 3/97 Ag 3 PO 4 /TiO 2 (in wt.% ratio) showed remarkably high photocatalytic activity in removal of gaseous 2-propanol (IP) and in evolution of CO 2 . Its photocatalytic behavior seemed to be caused by the inter-semiconductor hole-transfer between the valence band (VB) of Ag 3 PO 4 and TiO 2 .
