With TiO2-SiO2 composite oxide aerogel for the carrier, preparation a series of Ni/TiO2-SiO2 catalyst, and USES the N2 physical adsorption-to take off the attached, H2 program warming rection/take off with, X-ray diffraction and in-situ diffuse Fourier transform infrared spectroscopy technology characterized of catalyst, a visit to the carrier of titanium in content of catalyst structure, the surface properties and its catalytic maleic anhydride liquid choose hydrogenation gamma-irradiation butyl acetate synthesis in the influence on the performance of the reaction. The results show that the smaller Ni0 grain to gamma-irradiation within the generation of butyl acetate. In active catalyst is the rection of a process, as the carrier of titanium in the increase of the content of more and more TiO2 is reced to TiOx (x < 2) species. Ni0 grain and TiOx species synergy effect of hydrogenation catalyst carbonyl performance; When the smaller Ni0 grain properly matched TiOx species, catalytic ?

Ni0 grain and TiOx species synergy effect of hydrogenation catalyst carbonyl performance; When the smaller Ni0 grain properly matched TiOx species, showed high catalyst carbonyl hydrogenation activity.
