description: •The impact of SO42− doped Zn/Ce/TiO2 on antibacterial activity is investigated.•SO42−-doping can generate more surface hydroxyl groups.•Antibacterial activity of materials is due to improvement of the surface acidity. SO42−-doped Zn/Ce/TiO2 nano-materials (Zn/Ce/SO42−/TiO2) were prepared by a sol–gel method. The structures of Zn/Ce/SO42−/TiO2 nano-materials were characterized by Transmission electron microscope (T), X-ray diffraction (XRD), atomic absorption spectroscopy (AAS), X-ray photoelectron spectroscopy (XPS), X-ray photoelectron (PL) spectroscopy and Fourier transform infrared spectroscopy (FT-IR). Gram-negative Escherichia coli (ATCC25922) and Gram-positive Staphylococcus aureus (ATCC6538) as model organisms, antibacterial activities of nano-materials were tested using inhibition zone method and shaking flask method under visible light irradiation and in the dark. The results show that the materials crystal structure and elemental...
