摘要：SnS2/Bi2WO6 3D composite microstructure photocatalyst was fabricated through facile hydrothermal method. The 3D microstructure was self-assembled with hexagonal SnS2 nanosheets and Bi2WO6 nanoplates. The SnS2/ Bi2WO6 composite material showed improved photocatalytic activity than pure Bi2WO6 and SnS2. Photocatalytic efficiency of the optimized sample (4SS/BWO) was 99.94% for RHB and 86.45% for TC, which increased 83.26% and 44.38% compared with Bi2WO6, respectively. Additionally, the degradation efficiencies toward different pollutants declined in the following order: 99.7% (RhB)> 86.5% (TC)> 75.2% (SM)> 55.2% (MB)> 51.2% (CIP)> 50.5% (NOR)> 24.2% (MO). Moreover, the effect of environmental factors on the degradation of TC was investigated. Results showed that low solution concentration, high catalyst dosage and pH value led to higher removal efficiency. Existence of HCO3- and NO3 - in solution could enhance the degradation efficiencies, while the addition of cations (K+, Ca2+, Na+, Mg2+, Cu2+) and PO43- would restrict the degradation activity. The main active species during the photo degradation of TC was examined to be h+.
