Method for preparing mixed metal carbon-based composite material by using polyacid-based metal organic framework material

The invention relates to a method for preparing a mixed metal carbon-based composite material by using a polyacid-based metal organic framework material. The method comprises the following steps: carrying out in-situ template pyrolysis carbonization, vulcanization, phosphorization and other post-treatments on a prepared polyacid-based metal organic framework material to obtain a mixed metal carbon-based composite material. According to the invention, a series of porous carbon uniformly-loaded mixed metal composite materials with uniform pore diameters and adjustable sizes are prepared by selecting multi-acid@MOF materials with different pore structures as precursors and adopting a temperature programming-in-situ template pyrolysis and post-treatment method to develop surface modification and regulate and control the pore diameters at the same time, so that the cost is effectively saved, the period is shortened, and the defect of secondary pollution is avoided. 本发明涉及一种以多酸基金属有机框架材料制备混金属碳基复合材料的方法，将制备的多酸基金属有机框架材料
