High-specific-surface-area porous carbon material and preparation method thereof

The invention relates to the technical field of carbon material preparation, and particularly discloses a high-specific-surface-area porous carbon material and a preparation method thereof. The preparation method of the porous carbon material with the high specific surface area comprises the following steps: (1) mixing polypropylene, a catalyst and a thermal decomposition inorganic substance, and then carrying out melt extrusion granulation through a twin-screw extruder to obtain composite polypropylene particles; and (2) putting the composite polypropylene particles prepared in the step (1) into a heating device, heating to 600-900 DEG C, reacting for 1-3 hours, and washing a product after the reaction is finished, thereby obtaining the porous carbon material with high specific surface area. The method is simple in preparation process and relatively low in equipment requirement, and the prepared porous carbon material has relatively high specific surface area. 本发明涉及碳材料制备技术领域，具体公开了一种高比表面积多孔碳材料及其制备方法。所述的高比表面积多
