TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: In step (1), the acid modification treatment utilizes an acid modification material solution (A) with mass concentration of 40-75 % (preferably 60-65 %); and the alkali modification treatment utilizes an alkali modification material solution (B) with mass concentration of 10-50 % (preferably 28-32 %). In step (2), the platinum salt solution is added based on (1.6-6.4):1 (preferably 3.2:1) mass ratio of the activation pretreated mesophase carbon microsphere to the platinum salt; and the reducing agent solution is added based on (20-200):1 (preferably 100-150:1) mass ratio of the reducing agent to the platinum salt.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The acid modification material in the solution (A) comprises nitric acid, hydrogen peroxide (H2O2), phosphoric acid, sulfuric acid and/or hydrochloric acid (preferably mixed solution of nitric acid and hydrogen peroxide with (0.8-1.5):1 mass ratio); and the mass ratio of the acid modification material to the mesophase carbon microsphere is (1-15):1 (preferably (8-10):1). The alkali modification material in solution (B) comprises soluble hydroxide of sodium, soluble hydroxide of potassium, carbonate, bicarbonate, phosphate, hydrogen phosphate and/or dihydrogen phosphate (preferably sodium hydroxide (NaOH), sodium carbonate, sodium bicarbonate, potassium hydroxide, potassium carbonate and/or potassium bicarbonate); and the mass ratio of the alkali modification material to the mesophase carbon microsphere is (1-50):1 (preferably (30-35):1). The platinum salt in the solution (S1) consists of chloroplatinic acid, platinum potassium chloride, sodium platinate, platinum tetrachloride, sodium hydroxyplatinate, diaminedinitroplatinum ((Pt(NO2)2(NH3)2)) and/or platinum nitrate (preferably chloroplatinic acid). The reducing agent in the solution (S2) can also comprise sodium borohydride and/or preferably sodium hypophosphite.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The reducing agent solution (S2) has a mass concentration of 10-50 % (preferably 28-32 %); and the reducing agent comprises formaldehyde, ethylene glycol, sodium citrate, sodium formate, p-formaldehyde and/or ascorbic acid (preferably formaldehyde and/or ethylene glycol).
