【Abstract】The in-situ dynamic three-dimension FT-IR spectra of chemisorbed species of oxygen over metal oxides,such as MgO,CaO,La2O3,CeO2,Sm2O3,TiO2,ZrO2,V2O5,Nb2O5,Cr2O3,MnO2,Fe2O3,NiO,CuO,ZnO and SnO2,respectively,were investigated from room temperature to 650℃ Using our batch processing program for FT-IR dynamic spectra.The dependence of chemisorbed species of oxygen on tempareture and active oxygen species in oxidative coupling of methane(OCM) were discussed. For alkaline earth oxides and lanthanide earth oxides,a strong infrared band at the range of 1040～1160cm-1 was observed under reaction temperature of OCM,650℃.These bands were blue-shifted from room temperature to 650℃.The bands can be assigned to the chemisorbed species of oxygen,O2- acoording to the Nakamoto's assignment i.e.,1865(O2-)≈1580(O2)≈1097(O2-)≈766(O22-).There was scarcely and infrared band assigned to the species of O22- observed fro these oxides.For other transition metal oxides,however,the infrared band assigned to the species of O22- can be observed but the infrared band assigned to the species of O2- was scaroely observed.国家自然科学基金;福建炼油厂资
