英文摘要	molybdenum oxide supported on mordenite zeolite-alumina composite is post-treated by nitric acid leaching with varying periods (12-48h). the post-treated molybdenum catalysts display much higher stability for propene formation in 1-butene metathesis reaction. the evolution of mo species has been characterized by laser raman, (27)ai mas nmr and x-ray photoelectron spectroscopy. characterization results have shown the extraction of aluminum molybdates (al-2(moo4)(3)) after acid leaching post-treatment. this structural transformation relates to a transition in coke species on the spent molybdenum catalysts, and leads to the improvement in metathesis stability.
