Embodiment 1
[0036] Embodiment 1: provide a kind of Nb 0.8 Mo 0.2 o x Catalyst preparation method
[0037] a) 7.5g cetyltrimethylammonium bromide was dissolved in 7.5mL H 2 O, stirred at 40°C until completely dissolved. Recorded as solution A.
[0038] b) Weigh 8mmol NbCl 5 (2.161g) and 2mmol MoCl 5 (0.546g), gradually added to 10mL ethanol solution, stirred vigorously for about 10min. Recorded as solution B.
[0039] c) Add the B solution to the A solution dropwise, and further fully stir for about 30 min. This solution is denoted as C solution.
[0040] d) Prepare 10 mL of HCl aqueous solution with pH ≈ 1, and add it to the C solution. This solution is denoted as D solution.
[0041] e) Transfer the D solution to a hydrothermal kettle, and heat it at 160° C. for 24 hours.
[0042] f) After the hydrothermal kettle is lowered to room temperature, the product in the kettle is washed until neutral, and the solid product is separated by suction filtration.
[0043] g) The solid p...
