Example Embodiment
[0021] Example 1
[0022] Weigh 0.694 grams of Ni(NO 3 ) 2 ·6H 2 O, 0.138 g NH 4 VO 3 , Add 100ml deionized water to make a solution. Then, 0.222 g of oxalic acid was added to the solution, and magnetically stirred at 60° C. for 20-30 minutes until the solute was completely dissolved to prepare an active ingredient impregnation solution.
[0023] Weigh 2 grams of TiO 2 Powder carrier, immerse it in the active component impregnation solution, then transfer all the impregnation solution and carrier to an Erlenmeyer flask, completely evaporate the solution water at 70℃, then dry it at 110℃ for 12 hours, and roast at 500℃ In 5 hours, Ni with a metal element loading of 10% can be prepared 0.7 -V 0.3 / TiO 2 catalyst.
