Direct synthesis of dimethyl carbonate on H3PO4 modified V2O5

The catalytic properties and mechanism of H3PO4 modified V2O5 catalysts for the direct synthesis of dimethyl carbonate (DMC) from CO2 and CH3OH were investigated by means of DRIFT and XRD technologies, and the experimental results showed that the modified V2O5 catalysts were effective for the direct and selective synthesis of DMC from CO2 and CH3OH. The crystal phase of V2O5 influenced greatly on the reaction yield and selectivity of DMC.
