Mn2+ and Co2+ ions doped titania (TiO2) nanopowders were synthesized using organic acid precursor route for the first time. The results revealed that TiO2 with metal dopants were reduced grain size and increased the surface area of TiO2. The band gap energy values of doped TiO2 were higher than the pure TiO2 and show a blue shift. The photocatalytic performance of TiO2 in the degradation of the rhodamine B dye was tested. Moreover, the efficiency was enhanced by adding Mn and Co to TiO2.
