英文摘要	In this work, a simple chemical co-precipitation method was employed to prepare a series of excellent Z-type SrWO4@Bi2WO6 (SWO@BWO) heterojunction composites, in which SrWO4 was successfully assembled on Bi2WO6 nanosheets. The outstanding separation efficiency of photo-generated carriers (e(-)/h(+)) originated from synergetic effect of semiconductor heterojunctions under simulated sunlight effectively improved photocatalytic activity, resulting in a more prominent performance for organic dyestuff degradation compared with its counterparts. Based on the photocatalytic degradation of Methylene blue (MB) experiment, coming to a conclusion is that 10wt %SWO@BWO composite (eta=92.9 % for 50 min) has the prominent photocatalytic activity. The photocatalytic performance of 10wt %SWO@BWO composite is 6.36 and 2.6 times as high as that of bare SWO and BWO, respectively. This composite also has better degradation performance for Tetracycline Hydrochloride (TC) and Tetrabromobisphenol A (TBBPA). According to the active species capture experiment, (OH)-O-. are dominant in the degradation process of MB, and role of h(+) and O-.(2)- is also indispensable. Our research provides a simple approach for establishing Z-scheme heterojunction photocatalysts with great photocatalytic performance.
