NOVELTY - Transition metal- and nitrogen-containing macroporous carbon material is crushed to the grain size of 100-400 meshes, added to hydrothermal reaction kettle, and then benzotriazole and its derivatives are added to the kettle. An aqueous solution of transition metal-containing metal salt is then added to kettle, ultrasonically vibrated, and processed in oil bath. The resultant product is then filtered, washed using deionized water, and dried at 90 degrees C under vacuum condition, to obtain benzotriazole and its derivative-containing macroporous carbon loaded transition metal catalyst.    USE - Preparation of benzotriazole and its derivative-containing macroporous carbon loaded transition metal catalyst used as cathode for fuel cell or air battery.    ADVANTAGE - The method efficiently and economically provides benzotriazole and its derivative-containing macroporous carbon loaded transition metal catalyst having high durability, in short period of time.    DETAILED DESCRIPTION - Nano calcium carbonate is added to solution containing carbon source material, and urea and aqueous solution of transition metal salt are added, ultrasonically vibrated for 30 minutes, such that calcium carbonate disperses uniformly to form a suspension. The resultant suspension is subjected to spray drying process at 160-200 degrees C for 6 hours to form a cured product. The obtained cured product is subjected to constant-temperature carbonizing process at 600-900 degrees C under nitrogen atmosphere for 2 hours to form carbide carbonized product. The obtained carbonized product is processed using diluted hydrochloric acid at 80 degrees C, and washed using sodium hydroxide solution and deionized water. The resultant product is filtered, and dried at 120 degrees C for 4 hours to obtain transition metal- and nitrogen-containing macro-porous carbon material. The mass ratio of calcium carbonate, carbon source material, urea, and transition metal salt is 6 g: 6 g: 6 g:0.01-0.05 mol. The transition metal salt is nitrate, sulfate or chloride of transition metal element chosen from manganese, iron, cobalt, nickel, tin and/or copper. The obtained macroporous carbon material is crushed to the grain size of 100-400 meshes, added to hydrothermal reaction kettle, and then benzotriazole and its derivatives are added to the kettle. An aqueous solution of transition metal-containing metal salt is then added to the kettle, ultrasonically vibrated for 20 minutes, and processed in oil bath at 100-300 for 12 hours. The resultant product is then filtered, washed using deionized water, and dried at 90 degrees C under vacuum condition, to obtain benzotriazole and its derivative-containing macroporous carbon loaded transition metal catalyst. The ratio of nitrogen-containing macro-porous carbon material, benzotriazole and its derivatives and transition metal salt and water is 2 g:0.02-0.4 g:1.2-6 mmol:100 ml.
