Synergistic Effect of Amorphous Ti(IV)-Hole and Ni(II)-Electron Cocatalysts for Enhanced Photocatalytic Performance of Bi2WO6

Bi2WO6 has become a common photocatalyst due to its advantages of simple synthesis and high activity. However, the defects pure such as low light reception hinder application in photocatalysis. In this study, based on modification with Ti(IV) cavity co-catalyst, new Ni- Ti-doped nanosheets (Ni/Ti-Bi2WO6) were prepared by one-step wet thermal impregnation method used for photocatalytic degradation tetracycline. The experimental results showed that activity Ni/Ti-Bi2WO6 modified two-component catalyst was significantly better than those Ti-Bi2WO6 only. effect different Ni/Ti molar ratios investigated TC. 0.4Ni/Ti-Bi2WO6 possessed best performance, rate 92.9% at 140 min cycling experiments exhibited stability after five cycles. scavenger experiment demonstrated h+ O2− main reactive species. enhanced could be attributed synergistic between hole cocatalyst Ni(II) an electron cocatalyst, which effectively promoted separation photogenerated carriers.
