1. A method for preparing furfuryl alcohol by catalytic hydrogenation of furfural comprising hydrogenating the furfural in presence of the coordination zirconium phosphotungstate as a catalyst, wherein the method of making the coordination type zirconium phosphotungstate catalyst comprising: dissolving phosphotungstic acid and ZrCl4 in DMF respectively to obtain phosphotungstic acid solution and ZrCl4 solution; after ultrasonic treatment, adding phosphotungstic acid solution drop by drop into ZrCl4 solution within 5-30 min;
after uniform mixing, adding triethylamine; then reacting at room temperature for 3-6 hours; aging more than 4 hours; washing for 1-3 times with DMF, methanol, and anhydrous ether respectively;
and drying in vacuum at 70-100° C. for more than 8 hours.
