Porous electrode carbon material as well as preparation method and application thereof

The invention provides a preparation method of a porous electrode carbon material, which comprises the following steps: A) dissolving solid paraformaldehyde and an alkali reagent in water to obtain a formaldehyde solution; b) mixing m-cresol and the formaldehyde solution, adding an SBA-15 mesoporous molecular sieve and a base catalyst, and culturing gel at constant temperature to obtain wet gel; c) immersing the wet gel into a polyether solution, carrying out water replacement, and drying to obtain dry gel; and D) carbonizing the xerogel in a protective atmosphere to obtain the porous electrode carbon material. Compared with existing porous electrode carbon prepared through supercritical drying, on the premise that the problem of long-time storage of formaldehyde is solved, the preparation method is simple and low in cost, and industrial batch production can be achieved. The invention also provides a porous electrode carbon material and application thereof. 本发明提供一种多孔电极碳材料的制备方法，包括以下步骤：A)将固态多聚甲醛和碱试剂在水中溶解，得到甲醛溶液
