▎ 摘　　要

NOVELTY - Preparing carbon material catalyst comprises placing the catalyst precursor in the hot bed, where the catalyst comprises catalyst precursor and hot bed, the catalyst precursor includes an active metal and a transition metal compound to be replaced, and the catalyst precursor reaches a desired temperature in the hot bed to replace the highly active carbon material catalyst. USE - The method is useful for preparing carbon material catalyst. ADVANTAGE - The catalyst solves the problem that the low-cost and controllable preparation of carbon materials cannot be realized at present.
