Layered double hydroxides (LDHs) and their derivatives have been reported to be widely used as heterogeneous catalysts in various reactions. Herein, Ni‐Fe LDHs with the controlled Ni/Fe molar ratios (2:1, 3:1, 4:1) were synthesized via an easy hydrothermal method, which were used to catalyze the selective reduction of biomass‐derived furfural into furfuryl alcohol using 2‐propanol as a H‐donor under autogenous pressure and characterized using FT‐IR, XRD, TGA, BET, SEM, NH₃‐TPD, and CO₂‐TPD. It was found that the LDH with a Ni/Fe molar ratio of 3:1 demonstrated the best catalytic activity among the LDHs with different Ni/Fe molar ratios, which showed 97.0% conversion of furfural and 90.2% yield of furfuryl alcohol at 140°C for 5 hr. This was attributable to the synergistic effect of acidic sites and basic sites of the catalyst.

Ni-Fe层状双氢氧化物催化剂上糠醛催化转移加氢制糠醇

据报道，层状双氢氧化物（LDHs）及其衍生物被广泛用作各种反应中的非均相催化剂。在此，通过简单的水热法合成了具有受控的Ni / Fe摩尔比（2：1、3：1、4：1）的Ni-Fe LDH，这些催化剂可用于催化将生物质衍生的糠醛选择性还原为糠基在自生压力下使用2-丙醇作为氢供体的乙醇，并使用FT‐IR，XRD，TGA，BET，SEM，NH _3‐ TPD和CO _2进行表征-TPD。发现Ni / Fe摩尔比为3：1的LDH在不同Ni / Fe摩尔比的LDH中表现出最佳的催化活性，在140°C下糠醛转化率为97.0％，糠醇产率为90.2％。 C保持5小时。这归因于催化剂的酸性位点和碱性位点的协同作用。
