[0016] Method for preparing sec-butanol dehydrogenation MOF catalyst, its steps: weigh Cu (NO 3 ) 2 · 3h 2 O 25G and Zn (NO 3 ) 2 · 6h 2 O 15g is miscible in 200 ml of dimethylformamide and heated to 80 ° C, weigh Al (NO 3 ) 3 · 9h 2 O 3 g is dissolved in 100 ml of dimethylformamide and heated to 80 ° C, and 65 g of terephthalic acid was sungined in dimethylformamide dissolved in 500 ml of 80 ° C, and the Al salt solution was slowly added to benzene under vigorous stirring. In the dimethic acid solution, it was continued after completion of 2 h; in the above solution, the Cu-Zn mixed salt solution was added to the above solution, and then stirred after 2 h after addition, the above materials were transferred into the autoclave at 150 ° C for 20 h, resulting in a blue Substance, filtration, solid material drying at 120 ° C for 10 h, placed in a tubular furnace 5% o 5% o 2 / 95% N 2 Carbonization treatment for 5 h, get a black material, add 1G K 2 CO 3 The mix is uniform, which is...

[0020] Method for preparing sec-butanol dehydrogenation MOF catalyst, its steps: weigh Cu (NO 3 ) 2 · 3h 2 O 27G and Zn (NO 3 ) 2 · 6h 2 O 20G is miscible in 500 ml of dimethylformamide and heated to 80 ° C, AlCl 3 10 g is dissolved in 200 ml of dimethylformamide and heated to 80 ° C, and 85 g of terephthalic acid is soluble in dimethylformamide dissolved in 500 ml of 80 ° C, and the Al salt solution slowly adds the Al salt solution to benzene. In the formic acid solution, it was followed after 1 h after addition, and the Cu-Zn mixed salt solution was added to the above solution. After the addition is completed, stirring for 2 h, and the material was transferred into the autoclave at 200 ° C for 20 h, resulting in a blue material , Filtration, solid material drying at 120 ° C for 10 h, placed in a tubular furnace 5% by 450 ° C 2 / 95% N 2 Carbonization treatment for 5 h, get a black substance, add 1.5g K 2 CO 3 The mix is uniform, which is obtained.
