摘要：Ag-loaded ZnO mesocrystals with Fe3+ doped (PAZ) can be quantity-produced through an atmospheric self-induction synthesis method. This synthesis method avoids the use of a high-pressure instrument for the synthesis of mesocrystal catalysts. Compared with traditional Ag-ZnO catalysts, the threshold wavelength of 1FAZ mesocrystals was shifted to the full visible light region and the absorbance of catalyst in the visible region increased to more than 300%. The content of iron ion was found to be significant to the photocatalytic efficiency of FAZ mesocrystals. The experimental results demonstrated that the most optimal molar ratio of Fe3+ to Zn atoms was 1%, and the photocatalytic activity of 1FAZ mesocrystals was increased by 145% compared with Ag-ZnO obtained under visible light. A feasible water purification system with a continuous photodegradation reactor using PAZ mesocrystals was manufactured to utilize solar light as the energy to drive the running of the water purification system.
