The catalyst was used for the furfural carbonyl hydrogenation reaction to prepare furfuryl alcohol and 2-methylfuran, respectively. The results show that the particle size of catalyst support prepared by sol-gel method reaches the order of nanometers, CuO is highly dispersed in the carrier, and the grain size As a new non-Cr environment-friendly catalyst, it has the advantages of non-toxic, pollution-free, high activity and high selectivity. It can replace Cu-Cr catalyst for furfural hydrogenation and produce furfuryl alcohol and 2-methyl Furan
