TPR and TPD studies of vanadia/silica catalysts for selective oxidation of methane to formaldehyde
High selectivity of V2O5/SiO2 catalysts prepared from fumed silica, observed in oxidation of CH4 to HCHO at 550-590degreesC, was attributed to the content of highly dispersed, easily reducible surface vanadia species.
