[0030] see figure 1 , is a schematic flow chart of a method for preparing a porous carbon-supported ruthenium catalyst. The method comprises the steps of:
[0031] Disperse 5-10g serum protein powder in 50-100mL deionized water to obtain solution A;
[0032] Disperse 6-10g of zinc chloride in 50-100mL of deionized water to obtain solution B;
[0033] The solution B was added dropwise to the solution A, and stirred at 30-70° C. for 10 min to obtain a solution C;
[0034] 0.5-5mol L of 10-15mL -1 Sodium hydroxide solution was added dropwise to the solution C, and stirred at 30-70°C for 30 minutes to obtain a reaction solution;
[0035] drying the reaction solution at 80°C to obtain a powder;
[0036] Carry out carbonization of the powder under an argon atmosphere for 2 hours, the carbonization temperature is 600-900°C, and obtain a pre-product after cooling to room temperature;
[0037] The pre-product was subjected to 0.5-4mol L -1 Pickling with hydrochloric acid, suctio...
