Abstract

In order to utilize visible light more effectively, a novel Er 3+:Y3Al5O12/Bi2WO 6 photocatalyst was designed, in which Er3+:Y 3Al5O12 is a kind of upconversion luminescence agent and can emit ultraviolet light under visible light excitation. The photo-degradation of a typical model pollutant, phenol, demonstrated that Er3+:Y3Al5O12/Bi2WO 6 photocatalyst exhibited much enhanced photo-activity than bare Bi2WO6 under simulated solar light irradiation. Moreover, the Er3+:Y3Al5O12/Bi 2WO6 photocatalyst also showed photo-activity under visible light with wavelengths beyond the absorption edge of Bi 2WO6, further testifying the upconversion effect of Er3+:Y3Al5O12.
