Fig.7 presents the H2-TPR profiles of the M-OMS-2 catalysts..
Reduction of all the catalysts occurs in a temperature range of 170–350 °C.The peak position,area,and peak types vary among the catalysts (Table 1),indicating different influence of the doping metal on the OMS-2.These peaks between 200 °C and 350 °C can be ascribed to the hydrogen consumption during the formation of Mn2O3,the reduction of Mn2O3 to Mn3O4,and Mn3O4 to MnO [42].From Fig.7,one can readily observe that Cu-OMS-2 catalyst shows the highest reducibility with the largest H2 consumption (12.14 mol/g) and the lowest starting temperature of 170 °C,which might be caused by the reduction of Cu species [24].Furthermore,the Fe-OMS-2 and Cr-OMS-2 catalysts show lower reducibility with the smallest H2 consumption (10.80 and 10.73 mol/g,respectively),and higher starting reduction temperature (272 °C and 275 °C,respectively).The reducibility of the M-OMS-2 catalysts decreases in the following ord er:Cu-OMS-2 > Ni-OMS-2 >Co-OMS-2 > Cr-OMS-2 > Fe-OMS-2.The higher reducibility indicates the higher mobility of the oxygen species in catalysts.Therefore,Cu can significantly improve the oxygen mobility in OMS-2 catalyst compared with the other doping metals.The TPR results correlate fairly well with the catalytic combustion activities and the XPS results.Similar results have been reported for the silver modified OMS-2 catalysts in the CO oxidation reaction[43].Moreover,Hernández et al.[44] also suggested that Cu could improve the reducibility of OMS-2 and enhance the catalytic activity in preferential oxidation of CO.The promotion effect of Cu on the reducibility of OMS-2 could be attributed to the formation of Cu–O–Mn bridge and the hydrogen spillover from Cu atoms to manganese oxides [24,45].Combined with the XPS and H2-TPR results,it can be concluded that the highest catalytic activity of Cu-OMS-2 catalyst can be ascribed to the richer defect-oxide species and the higher reducibility or oxygen mobility.Benzyl alcohol oxidation over OMS-2 catalyst has been proposed to obey the Mars–van-Krevelen (MVK) mechanism [31].
