Synthesis and Characterization of Sn/Ni Single Doped and Co–Doped Anatase/Rutile Mixed–Crystal Nanomaterials and Their Photocatalytic Performance under UV–Visible Light

Pure and Sn/Ni co–doped TiO<sub>2</sub> nanomaterials with anatase/rutile mixed crystal were prepared and characterized. The results show that pure TiO<sub>2</sub> is a mixed crystal structure composed of a large amount of anatase and a small amount of rutile. Sn doping promo...
