The XPS and TPR showing dopants exist as divalent and trivalent ions for M n+ /TiO 2 , where M=Co, Ni, Mn, and as monovalent and divalent ions in the case of Cu/TiO 2 . ...
The TPR analysis showed that reduction behaviors of the M n+ /TiO 2 were strongly affected by the synthesis method, preparation conditions and interactions between the dopant metal and TiO 2 matrix. ...
Also, the temperature of the high-temperature peak (375 °C) coincides that found in the work [54] , and it may be indicative of stepwise reduction process. ...
