[0029] Preparation of filter residue:
[0030] Put graphite powder and sulfuric acid solution with a mass fraction of 80% into a beaker at a mass ratio of 1:10, place the beaker in an ice-water bath, mix and stir with a stirrer at a speed of 500r / min for 40min to obtain a suspension, and pour it into the beaker Add potassium permanganate powder with 5% mass of the suspension, increase the temperature of the water bath to 35°C, continue stirring for 30 minutes, and then filter to obtain a filter residue.
[0031] Preparation of dry product:
[0032] Put the above filter residue and hydrogen peroxide with a mass fraction of 20% into a beaker at a mass ratio of 1:10, place the beaker in an ultrasonic oscillator, vibrate for 100 min at a frequency of 35 kHz to prepare a mixed solution, and add 50 mL of The reducing solution was obtained by passing hydrogen gas at a rate of 1 / min for 60 minutes, and the reducing solution was filtered to obtain the filter residue. The filter residu...
