| Abstract: | Gas-phase oxidation of methacrolein to methacrylic acid has been carried out over various unsupported and supported H4PMo11VO40 catalysts. While SiO2-supported H4PMo11VO40 showed low selectivity to methacrylic acid, H4PMo11VO40 supported on NH3-modified SiO2, which was prepared by using an impregnation method with acetone as the solvent, exhibited high selectivity (∼90%) and high activity for the formation of methacrylic acid. The activity of H4PMo11VO40/NH3-modified SiO2 was more than five times higher than that of the corresponding unsupported catalysts. |
