Embodiment 1
[0024] Prepare 0.1M KOH, 0.15M K 2 SO 4 Mix the solution with 0.01M polyvinyl alcohol, place the copper electrode in the above mixed solution, ultrasonically treat it in the ultrasonic oscillation pool for 0.5h, then take it out and dry it naturally; prepare 0.03-0.1M 1-butyl-3 methyl A mixed solution of imidazolium bromide in methanol and ethanol, add 0.06-0.12M trimesic acid and 0.2-0.5M ethylenediaminetetraacetic acid (EDTA) and diethylenetri Amine (DEA), continue stirring. The treated copper electrode is used as the anode, and the platinum electrode is used as the cathode, and electrolyzed at 10.2-14.6V for 0.5-2.5h at room temperature to obtain Cu 3 (BTC) 2 catalyst, the resulting Cu 3 (BTC) 2 The catalyst was washed repeatedly with ethanol, dried, and 2 Activated at 200-280°C for 2 hours under protection to obtain active Cu 3 (BTC) 2 catalyst.
Embodiment 2
[0026] Prepare 0.3M KOH, 0.15M K 2 SO 4 Mix the solution with 0.03M polyvinyl alcohol, treat it with an ultrasonic copper electrode at 100W in an ultrasonic oscillation pool for 1 hour, and then take it out to dry naturally.
Embodiment 3
[0028] Prepare 0.5M KOH, 0.15M K 2 SO 4 Mix the solution with 0.05M polyvinyl alcohol, treat it with an ultrasonic copper electrode at a power of 100W in an ultrasonic oscillation pool for 2 hours, and then take it out to dry naturally.
