Embodiment 1
[0055] with RuCl 3 is the ruthenium source, CH 3 COONa is surfactant, and ethylene glycol is solvent and reducing agent, and its synthetic method is as follows:
[0056] 1. Take 20.74mg RuCl 3 and 26mg CH 3 COONa was dissolved in 30 mL of ethylene glycol solution, then stirred and ultrasonically uniform, the temperature of the mixed solution was raised to 140 °C and kept for 90 min, then the heating was stopped, and the temperature was cooled to room temperature.
[0057] 2. Weigh 40mg of carbon powder and dissolve it in 30mL of ethylene glycol solvent, then ultrasonically stir for 30min, then add the solution after the reaction in step 1 dropwise into carbon-containing ethylene glycol, then ultrasonically for 1h, and stir for 2h, The nanoparticles are uniformly loaded in the carrier material.
[0058] 3. Wash the mixed solution obtained in step 2 with absolute ethanol solution, remove ethylene glycol by suction filtration, and finally place the obtained filter cake in a v...
Embodiment 2
[0061] Take Ru(acac) 3 is the ruthenium source, CH 3 COONa is surfactant, and triethylene glycol is solvent and reducing agent, and its synthetic method is as follows:
[0062] 1. Take 39.84mg Ru(acac) 3 and 10mg CH 3 COONa was dissolved in 40 mL of triethylene glycol solution, and the mixed solution was heated to 230 °C for 5 h, then the heating was stopped and it was lowered to room temperature.
[0063] 2. Take 40 mg of activated carbon powder and dissolve it in 50 mL of triethylene glycol solution, then add the reaction solvent obtained in step 1 dropwise into the carbon-containing triethylene glycol solution, then sonicate for 1 hour, and stir for 3 hours, so that the obtained carbon Ruthenium nanoparticles are uniformly distributed.
[0064] 3. Then add 100 mL of absolute ethanol to wash, then perform suction filtration, and place the obtained sample in a vacuum drying oven at 80°C for drying.
[0065] 4. Place the sample obtained in step 3 in a mortar for grinding,...
Embodiment 3
[0067] with RuCl 3 Be ruthenium source, polyvinylpyrrolidone (PVP, average molecular weight is 58000) is tensio-active agent, and propylene glycol is solvent and reducing agent, and its synthetic method is as follows:
[0068] 1. Take 21mg RuCl 3 Dissolve 55mg of PVP in 30mL of propylene glycol solution, then ultrasonically stir for 20min, heat the uniformly mixed solution to 160°C for 2h, then stop heating, and cool down to room temperature.
[0069] 2. Dissolve 40mg of carbon powder in 50mL of propylene glycol solution, then ultrasonically stir for 30min, then add the reaction solvent obtained in step 1 dropwise into the above mixed solution, then stir for 3h, ultrasonically for 2h, and evenly load the nanoparticles on the on a carbon support.
[0070] 3. Add 100 mL of absolute ethanol solution to the solution obtained in step 2 for washing, and then perform suction filtration. This step is repeated 3 times, and then place the formed filter cake in a vacuum drying oven at ...
