Embodiment 1
[0022] Catalyst preparation:
[0023] Put 1.000g of activated carbon and 5ml of 1,1-cyclobutanedicarboxylic acid benzene solution in a dilute acid solution with a pH of 3 prepared by sulfuric acid, add 0.2g of Anderson type ammonium zinc molybdate heteropolyacid, 1ml of N-methylpyrrolidone , magnetically stirred at room temperature for 24 hours, then ultrasonically oscillated for 1 hour, moved into a hydrothermal reaction kettle, and used a temperature-programmed oven to raise the reaction temperature from room temperature to 150°C within 1 hour, and maintained the temperature for 48 hours, and then naturally cooled to At room temperature, rinse with ultrapure water and ethanol several times, filter, and dry for 12 hours to obtain samples for later use.
