英文摘要	a series of mo-based catalysts for 1-butene metathesis to propene were prepared by supporting mo species on sba-15 premodified with alumina. the effects of the method of introduction of the alumina guest to the host sba-15 on the location of the mo species and the corresponding metathesis activity were studied. as revealed by n-2 adsorption isotherms and tem results, well-dispersed alumina was formed on the pore walls of sba-15 if the ammonia/water vapor induced hydrolysis (nih) method was employed. the mo species preferentially interacted with alumina instead of sba-15, as evidenced by x-ray photoelectron spectroscopy, time-of-flight secondary-ion mass spectrometry, and ir spectroscopy of adsorbed pyridine. furthermore, new bronsted acid sites favorable for the dispersion of the mo species and low-temperature metathesis activity were generated as a result of the effective synergy between the alumina and sba-15. the mo/al2o3@sba-15 catalyst prepared by the nih method showed higher metathesis activity and stability under the conditions of 120 degrees c, 0.1mpa, and 1.5h(-1) than catalysts prepared by other methods.
