Embodiment 1
[0028] 1. Activation treatment of carbon nanotubes (provided by the Department of Chemical Engineering, Tsinghua University)
[0029] (1) Water washing: put carbon nanotubes into a round bottom flask, moisten with absolute ethanol, then add a certain amount of double distilled water, heat to boil, reflux for 1 hour, filter, and dry at 80°C for 2 hours to obtain water-washed activated carbon nanotube samples.
[0030] (2) pickling: soak the water-washed activated carbon nanotube sample with 10% hydrochloric acid for 10 hours, reflux for 1h, filter, and wash with water until there is no Cl - Dry at 80°C for 2 hours.
[0031] 2. Preparation of Pt / CNTs catalyst
[0032] (1) Weigh 1.5068 grams of activated carbon nanotubes, add them to a round bottom flask, add a certain amount of absolute ethanol dropwise to moisten, then add 80 mL of double distilled water, and stir for 5 minutes;
[0033] (2) Add the prepared chloroplatinic acid solution (1 gram of chloroplatinic acid dissolv...
