Embodiment Construction
[0024] Specific implementation 1:
[0025] (1) Add the surfactant and the reducing agent into the aqueous solution at a mass ratio of 2:3, and stir for 15 minutes;
[0026] (2) Add chloroplatinic acid solution and ruthenium trichloride solution with a volume ratio of 3:2 to the mixed solution (5.6mL) in step (1), both at a concentration of 0.1mol / L, and the color of the mixed solution is yellow-brown , stirring at room temperature for 15 minutes;
[0027] (3) Transfer the solution obtained in step (2) into the reactor, react for 2 hours, and control the temperature at about 200°C;
[0028] (4) The obtained product is separated by centrifugation and washed three times with alcohol solution, and then dispersed and stored in alcohol solution, with good dispersibility and general catalytic activity.
[0029] Specific implementation 2:
[0030] (1) Add the surfactant and the reducing agent into the aqueous solution at a mass ratio of 2:3, and stir for 20 minutes;
[0031] (2) A...
