The dye wastewater produced in the printing and dyeing industry causes serious harm to the natural environment. TiO 2 usually shows photocatalytic degradation of dye under the irradiation ultravilet light rather than visible light. In this work, a large number of oxygen vacancies and Ti 3+ defects were generated on the surface of the TiO 2 nanoparticles via Ar plasma. Compared with pristine TiO 2 nanoparticles, the as-obtained Ar plasma-treated TiO 2 (Ar-TiO 2 ) nanoparticles make the energy band gap reduce from 3.21 eV to 3.17 eV and exhibit enhanced photocatalytic degradation of organic dyes. The Ar-TiO 2 obtained exhibited excellent degradation properties of methyl orange (MO); the degradation rate under sunlight irradiation was 99.6% in 30 min, and the photocatalytic performance was about twice that of the original TiO 2 nanoparticles (49%). The degradation rate under visible light (λ &gt; 400 nm) irradiation was 89% in 150 min, and the photocatalytic performance of the Ar-TiO 2 was approaching ~4 times higher than that of the original TiO 2 nanoparticles (23%). Ar-TiO 2 also showed good degradation performance in degrading rhodamine B (Rho B) and methylene blue (MB). We believe that this plasma strategy provides a new method for improving the photocatalytic activity of other metal oxides.
