By calcinating commercial silica gel at 1500℃or adding Na2C2O4 and then calcinating at 850℃,α-cristobalite was formed. On the basis of the vibration spectroscopy of silica support, Na-W-Mn/SiO2 catalyst was characterized by Raman spectroscopy. The results show that the structure of support and the interaction among metal components have significant effect on the dispersion and the structure of metal sites, and the tetrahedrally coordinated [WO4] formed on α-cristobalite surface is the most possible site of methane activation with high C2 selectivity.
