Photocatalytic degradation of imidacloprid by optimized BiWO/NH-MIL-88B(Fe) composite under visible light.

Imidacloprid as a widely used neonicotinoid insecticide can cause harmful pesticide residue inevitably. Metal-organic frameworks (MOFs) were innovatively composited to improve the light absorption and degradation performance of BiWO semiconductor, which expanded the photodegradation application in solving environmental problems. Based on the synergistic effect of BiWO and NH-MIL-88B(Fe), a BiWO/NH-MIL-88B(Fe) (BNM) heterojunction photocatalyst with high-performance of photocatalytic degradation activities was successfully synthesized.
