Herein, porous N,S co‐doped TiO 2 nanoparticle (N,S‐TiO 2 ) with the high specific surface area were successfully obtained by a simple oil bath reaction and annealing post‐treatment. Especially, abundant nitrogen and sulphur elements were co‐doped into the resulted TiO 2 nanoparticles, which greatly improved the visible light absorption ability of the material. The obtained products were characterised by scanning electron microscope, transmission electron microscopy, Brunauer–Emmett–Teller, X‐ray diffraction, Fourier transform‐infrared spectroscopy, ultraviolet–visible diffuse reflectance spectra and X‐ray photoelectron spectroscopy, respectively. In addition, the obtained N,S‐TiO 2 exhibited superior tetracycline photocatalytic degradation activity, which can reach 84.9% within 60 min under irradiation of visible light and preserved excellent stability even after five recycles. Furthermore, the possible formation process of N,S‐TiO 2 was discussed. In brief, the obtained N,S‐TiO 2 can be used as a potential candidate for visible light‐driven photocatalysis.
