英文摘要A novel 0D/3D CdTe quantum dots/Bi2WO6 (CTQDs/BWO) Z-scheme photocatalyst was designed to enhance photochemical energy conversion efficiency. Experimental results demonstrated that the CTQDs/BWO injected electron lifetime, interfacial carrier transfer efficiency, and visible light absorption ability were observably enhanced due to the quantum effect and Z-scheme heterojunction synergy. In particular, 1.0 % CTQDs/BWO displayed excellent tetracycline removal efficiency (91.45 %) and prominent E. coli photoinactivation under visible light. In addition, its tetracycline removal efficiency remained above 85 % after five cyclic experiments. Moreover, using density functional theory (DFT) calculations and LC-MS spectra, we deeply analyzed the photoinduced electron transfer pathways and photocatalytic reaction degradation pathways and proposed a Z-scheme heterojunction model. This work provides a novel strategy for designing efficient Z-scheme photo catalysts and exhibits promising prospects for utilizing photocatalysts to address water contaminants.
