摘要
In this work, highly dispersed and low-metal loading CuOx@BiVO4 nanocomposites were fabricated via a multistep method. The fabricated samples exhibited excellent stability and a dependent tetracycline hydrochloride photocatalysis degradation efficiency on CuOx loading ratio, among which 0.4 %CuOx loading sample displayed best photocatalytic performance under visible light illumination. The loading CuOx significantly broadened the spectrum absorption range, enhanced the photogenerated electron-hole pairs separation and facilitated the formation of ·O2– and ·OH in CuOx@BiVO4. Moreover, the trapping experiments proved the crucial roles of h+, ·OH and ·O2– in the photodegradation process. Finally, a plausible photocatalytic mechanism has been proposed based on all analytical results.
