摘　　要：以Cu基金属有机框架(MOF)负载RuCl 3,采用氢气还原法和真空碳热还原法制备Ru-Cu@C催化剂。以异丙醇为氢供体,研究Ru-Cu@C催化糠醛转移加氢制糠醇性能,考察催化剂制备方法、Ru负载量及催化反应条件的影响。结果表明,与氢气还原法相比,采用真空碳热还原法制备的Ru-Cu@C催化剂表现出更高的糠醛催化转移加氢活性和稳定性,T=453 K反应4 h,糠醛转化率93.7%,糠醇选择性98.2%,催化剂经5次循环使用后仍保持高的催化活性。Using Cu-based metal-organic frameworks loaded with RuCl 3,Ru-Cu@C catalysts were prepared by hydrogen reduction and vacuum carbothermic reduction,respectively.The catalytic transfer hydrogenation of furfural to furfuryl alcohol of the as-obtained catalysts was evaluated using isopropanol as hydrogen donor.The effects of preparation method,Ru loading,and catalytic reaction conditions were studied.The results showed that the vacuum carbothermic reduction-derived Ru-Cu@C catalyst shows higher catalytic activity and stability than the hydrogen reduction-derived catalyst.The furfural conversion was 93.7%and the furfuryl alcohol selectivity was 98.2%after 4 h at 453 K.The catalytic performance did not decrease significantly after reuse for five times.
