英文摘要	Cs-salts of the keggin-type phosphomolybdic acid with simultaneous doping of vo2+ and different transition metals are prepared, characterized and tested as catalysts for the oxidation of isobutane to methacrylic acid under isobutane-rich conditions. the results show that cs2.0v0.3cu0.2pmo12o40 catalyst with co-substituted vo2+ and cu2+ in its secondary structure exhibits higher catalytic performance than those with co-doped vo2+ and other transition metals such as fe, ni and ce. this difference is ascribed to the synergistic effect between cu2+ and vo2+ only in the secondary structure. this synergistic effect is related to the charge transfer between mo6+ in the keggin anions and cu2+ counter cation, which promotes the re-oxidation of the catalyst and consequently its catalytic activity.
