SILVER PHOSPHATE BASED PLASMONIC PHOTOCATALYST: HIGHLY ACTIVE VISIBLE-LIGHT-ENHANCED PHOTOCATALYTIC PROPERTY AND PHOTOSENSITIZED DEGRADATION OF POLLUTANTS

Abstract

A stable silver phosphate based plasmonic photocatalyst ( Ag-Ag3PO4 ) was successfully fabricated, which can drive catalytic reaction under low-intensity visible light. The synthesized plasmonic photocatalyst shows high performance and stability on the photodegradation of RhB under visible-light irradiation, and represents obviously enhanced photocatalytic activity than the pure Ag3PO4 sample. The photosensitization process was carried out in the photodegradation of 2,4-DCP and RhB mixture, of which the photocatalyst shows the enhancement activity for 2,4-DCP while weaker for RhB . The investigation is likely to open up a new sight for the preparation of high efficient and stable plasmonic photocatalysts which utilizes visible light.
