Nanocrystalline AMn2O4 (A = Co, Ni, Cu) manganite spinels were prepared by using the sol–gel auto combustion method under the same
synthesis conditions and their physico-chemical properties were studied by XRD, UV–vis DRS, SEM, BET and FTIR. Besides, the reducibility of
oxides was studied by temperature-programmed reduction (TPR). The relationship between the properties and activity of spinels in oxidation of 2-
propanol and toluene was investigated. Among all, nickel manganite exhibited the most promising activity, in which the completed conversion of 2-
propanol and toluene occurred at 250 and 350 8C, respectively. Higher activity of nickel manganite oxide was explained …
