摘要: Mo–V–Te–P mixed oxide catalysts, prepared by a dry-up method at various pHs (in the range of about 1.0–9.0), have been tested in partial oxidation isobutane. The best catalytic performance was achieved over catalyst pH 7.0. In this case, high selectivity to methacrolein (37.0%) an isobutane conversion 12.7% has obtained 380 °C. surface V4+/V5+ ratios calcined samples were strongly influenced synthesized solution, which is one key factors for selective
