摘　　要：采用简单易行的常压液相合成法,通过调节氧氯化锆和均苯三甲酸的比例,制备得到MOF-808-x,利用X-射线衍射(XRD)、傅里叶红外光谱(FT-IR)、场发射透射电子显微镜(TEM)等对其结构、形貌进行一系列表征。以糠醛加氢为探针反应,考察了MOF-808-x在异丙醇为氢供体体系中催化糠醛转移加氢制糠醇反应性能,并优化了反应条件。结果表明:合成催化剂适宜的原料配比可以提高反应活性。以MOF-808-1为催化剂时,在100℃反应2 h,糠醛转化率为100%,糠醇选择性>99%。MOF-808-x was prepared by a simple liquid phase synthesis method under atmospheric pressure,by adjusting the ratio of zirconium oxychloride and trimesic acid.The structure and morphology of MOF-808-x were characterized by X-ray difraction(XRD),fourier infrared spectroscopy(FT-IR)and field emission transmission electron microscopy(TEM).Using furfural hydrogenation as probe reaction,the catalytic performance of MOF-808-x for furfural transfer hydrogenation to furfural alcohol in isopropyl alcohol as hydrogen donor system was investigated,and the reaction conditions were optimized.The results showed that the appropriate ratio of raw materials could improve the reaction activity.With M0F-808-1 as catalyst,the furfural conversion rate was 100%and furfuryl alcohol selectivity was>99%at 100℃ for 2 h.
