不同晶型TiO2负载镍催化剂催化顺酐液相加氢
Liquid Phase Hydrogenation of Maleic Anhydride over Ni/TiO2 Catalysts with Different TiO2 Polymorphs
摘要
Abstract
Ni/TiO2 catalysts with anatase and rutile titania as supports were prepared via the incipient impreg-nation method and were applied in the liquid phase hydrogenation of maleic anhydride. All catalysts were characterized by N2 physical adsorption-desorption, H2-temperature programmed reduction(H2-TPR), X-ray diffraction(XRD), H2-temperature programmed desorption(H2-TPD) and X-ray photoelectron spectroscopy ( XPS) . The evaluation results show that the activity of CO hydrogenation of catalyst with anatase TiO2 as support was significantly higher than that with rutile TiO2 as support. The higher activity of CO hydrogena-tion was attributed to a higher concentration of the oxygen vacancies produced during the reduction process. Oxygen vacancies could promote the hydrogenation of CO group by accepting lone pair of electrons of oxy-gen in CO group.关键词
