The invention belongs to the field of preparation processes of nano-porous materials, and relates to a preparation method of an in-situ growth palladium-based alloy loaded N-doped carbon aerogel electro-catalytic material. Palladium salt, non-palladium salt, water, phenol and aldehyde are mixed, then sodium carbonate serves as a coagulant, then aging, supercritical drying and high-temperature heat treatment are conducted, palladium-based alloy is loaded on the surface of nitrogen-doped carbon aerogel in situ, and the high catalytic activity and stability of the palladium-based alloy and the high specific surface area and dispersity of the carbon aerogel are effectively utilized. The method has the advantages of low cost and convenient process, and is low in energy consumption, simple in process and easy to realize large-scale production. 本发明属于纳米多孔材料的制备工艺领域，涉及一种原位生长钯基合金负载N掺杂碳气凝胶电催化材料的制备方法。通过将钯盐、非钯盐、水、酚、醛进行混合，然后以碳酸钠作为促凝剂，后经老化、超临界干燥和高温热处理过程，在氮掺杂碳气凝胶表面原位负载钯基合金，有效利用钯基合金的高催化活性和稳定性和碳气凝胶的高比表面积及分散性。本发明具有成本低廉和工艺便捷的优点，同
