Abstract: In order to improve the visible photocatalytic and antibacterial properties of TiO₂/ZSM-5, CuO/TiO₂/ZSM-5 composites with visible photocatalytic and antibacterial properties were prepared by impregnation-calcination method using Cu(NO₃)₂, Ti(SO₄)₂ and ZSM-5 as raw materials. X-ray diffraction analyzer (XRD), X-ray photoelectron spectrometer (XPS), gas adsorption instrument, scanning electron microscopy-energy spectrometer (SEM-EDS), UV-visible diffuse reflection spectrometer (UV-Vis DRS), X-ray fluorescence spectrometer (PL), electron paramagnetic resonance spectrometer (EPR) and inductively coupled plasma emission spectrometer (ICP) were used to characterize the composition of the material. The photocatalytic property of the material was evaluated by methyl orange solution, and the antibacterial property of the material was evaluated by Escherichia coli and Staphylococcus aureus. The results show that the CuO/TiO₂/ZSM-5 composites with high specific surface area and pore volume can be synthesized by impregnation-calcination method. When the molar ratio of CuO/TiO₂ is 0. 5 %, the as-prepared 0. 5CuO/TiO₂/ZSM-5 sample has a relatively lower electron-hole recombination rate, a wide photoresponse range, and a high production amount of active species such as ·O₂^- and ·OH, and exhibiting excellent photocatalytic and antibacterial properties. The removal rate of methyl orange reaches 95 % after 150 min illumination under xenon lamp, and the antibacterial rates of Escherichia coli and Staphylococcus aureus reach 75. 2 % and 83. 3 %, 97. 6 % and 98. 5 % under dark condition and illumination for 5 min, respectively.
