Abstract

The kinetics of oxidation of CH4 to formaldehyde on the catalytic system Na4[PFeMo11O40]/SiO2 were studied, and a significant role of the redox potential of the CH4-O2 system with respect to the catalyst was shown. The density of centers participating in the reaction was determined, and dissociative competitive adsorption of methane and oxygen was established. The equation was deduced in the framework of the Langmuir-Hinshelwood theory taking into account the side conversion of formaldehyde. Possible participation of lattice oxygen in the reaction was suggested.
