Abstract:
The invention discloses a coordination type zirconium phosphotungstate catalyst and its application in catalytic hydrogenation of furfural, belonging to the field of heterogeneous catalysis. The zirconium phosphotungstate catalyst prepared by the invention not only has good catalytic effect on the conversion of furfural to furfuryl alcohol, but also has mild reaction conditions. The yield of solid line furfuryl alcohol can be 98% if it can be reacted for 1 h at 120 ° C., and the amount of catalyst is less, which greatly reduces the energy consumption in the prior art. In addition, the zirconium phosphotungstate prepared by the invention is easy to separate, has good stability for catalyzing the hydrogenation of furfural to furfuryl alcohol, and is a new, efficient and green catalyst.
