- ... Nitrogen and zirconium co-doped TiO₂ (TiO₂–N–x%Zr) photocatalysts were synthesized via a sol–gel method. The existing states of the dopants (N and Zr) and their corresponding band structures were investigated via XRD, Raman, BET, XPS, TEM, FT-IR, UV–vis DRS, and PL techniques. It was found that N existed only as a surface species (NOₓ) and Zr⁴⁺ was doped in a substitutional mode; the doping of Zr⁴ ...
