不同溶剂体系制备的Co-B催化剂应用于糠醛选择性加氢制备糠醇

选用不同溶剂配制CoCl2溶液，由化学还原法制备了一系列Co-B非晶态合金催化剂，这些催化剂在糠醛选择性加氢制备糠醇反应中均显示高选择性(接近100％)，而乙醇介质中制得的Co-B催化剂，其催化活性显著高于其他溶剂所制备的催化剂、结合表征，初步探讨了不同溶剂对催化剂的结构、电子态以及催化性能的影响．

Solvent effects in preparing Co-B catalyst and its application in the selective hydrogenation of Furfural to Furfuryl alcohol

In this article, a series of Co-B catalysts were prepared by chemical reduction of CoCl2 with KBH4 in different media. The catalysts displayed high selectivity to furfuryl alcohol (near 100% ) in Liquid phase furfural hydrogenation. The Co-B catalyst obtained in ethanol solution exhibited higher activity than the other Co-B catalysts obtained in other media. Based on various characterizations, the effects of media used for catalyst preparation on both the structure and the surface electronic states of the as-prepared catalysts were examined. Meanwhile, the correlation of catalytic properties to the structural and electronic characteristics was also discussed briefly.
