Abstract

Abstract : We report a heterojunction photocatalyst by coupling CdS with Bi12 O17 Cl2 via a facile thermal annealing process. Such heterostructure can promote the charge separation between CdS and Bi12 O17 Cl2, thereby leading to a considerable improvement on the performance for CO2 reduction into valuable CH4 and phenol conversion under visible light exposure. The CdS/Bi12 O17 Cl2 heterojunction with mass ratio of 1 : 1 (50% CdS/Bi12 O17 Cl2 ) shows the highest CH4 production rate (1.28 μ mol·h -1 ·g -1 ), which is as 9.8 and 5.8 times as the CH4 generation rate of pure Bi12 O17 Cl2 and CdS (0.13 and 0.22 μ mol·h -1 ·g -1 ), respectively. Also, the 50% CdS/Bi12 O17 Cl2 sample shows the highest activity of phenol conversion with a conversion ratio of 92%, which is as 2.2 times and 1.9 times as the conversion ratio of pristine Bi12 O17 Cl2 (41%) and CdS (48%), respectively. The present study demonstrates the great potential of the CdS/Bi12 O17 Cl2 heterojunction for efficient charge separation towards increased photocatalytic CH4 production and phenol conversion.
