Embodiment 1
[0021] Take 0.2 grams of carbon carrier and place it in a flask filled with 10ml of sulfuric acid, heat it while stirring, and reflux the sulfuric acid. After 6-12 hours of treatment, filter and wash the carrier until it is neutral, and dry it for later use; configure a concentration of 20mmol / L Ruthenium chloride solution, 5ml of chloroplatinic acid solution with a concentration of 20mmol / L; 30ml of isopropanol, 25ml of cyclohexane, and 10ml of surfactant triton-100 were mixed and stirred for 30 minutes to form a transparent microemulsion system, and 20mmol / L was added 5 ml of ruthenium chloride of 1 L, and a small amount of n-butanol was added dropwise, placed in a microwave oven for intermittent microwave treatment (the total power of the microwave oven was 800w) after mixing evenly, utilized 10% power to heat for 20 seconds, heated four times, and then used 30 % power heating for 10 seconds, heating three times, every two heating intervals of 15 seconds, stirring; observe t...
Embodiment 2
[0023] Take 0.2 grams of carbon carrier and place it in a flask filled with 10ml of sulfuric acid, heat it while stirring, and reflux the nitric acid. After 6-12 hours of treatment, filter and wash the carrier until it is neutral, and dry it for later use; configure the concentration of 20mmol / L Ruthenium chloride solution, concentration are each 5ml of the chloroplatinic acid solution of 20mmol / L; With 40ml n-heptane, 0.35gCTAB (hexadecyltrimethylammonium bromide), mix and stir 30 minutes to form transparent microemulsion system, add Ruthenium chloride 5ml of 20mmol / L, and a small amount of n-butanol is added dropwise, is placed in the microwave oven after mixing uniformly and carries out intermittent microwave treatment (microwave oven total power is 800w), utilizes 10% power to heat 20 seconds, heats four times, again Heat at 30% power for 10 seconds, three times, stirring for fifteen seconds in between. It was observed that the microemulsion changed from light gray to ligh...
