Mg2+ and Zr4+ co-doped TiO2 was synthesized by sol–gel method. Catalysts were characterized by XRD, UV–vis DRS, SEM-EDX, TEM, BET, XPS and FT-IR to evaluate the crystal patterns and crystallite size (5.07–18.9 nm), bandgap energy, morphology, surface area, surface composition with oxidation states and incorporation of dopants into TiO2 lattice. Degradation of methylene blue was carried out under visible light irradiation by varying the reaction parameters such as initial dye concentration, catalyst loading and pH of the solution. 1.0 wt% Mg2+ and 0.25 wt% Zr4+ codoped TiO2 was found to be an efficient catalyst.
