The invention discloses application of a palladium-doped nano porous nickel/nickel oxide composite material in catalytic hydrogenation reaction of p-nitrophenol. Through chemical corrosion of an AlNiPd alloy strip, the palladium-doped nano-porous nickel/nickel oxide composite material is directly obtained. The composite material has a three-dimensional through porous structure and palladium dispersed in a nickel/nickel oxide matrix in a sub-nanometer scale. The material shows excellent solution catalytic hydrogenation activity, and hydrogenation reduction reaction of sodium borohydride solutions with different concentrations on a substrate can be realized. Therefore, the material disclosed by the invention is simple to prepare and outstanding in catalytic hydrogenation reaction activity, and has a good application prospect in the fields of p-nitrophenol wastewater treatment and p-aminophenol preparation. 本发明公开一种钯掺杂纳米多孔镍/氧化镍复合材料在对硝基苯酚催化加氢反应中的应用。通过AlNiPd合金条带的化学腐蚀，直接得到钯掺杂纳米多孔纳米多孔镍/氧化镍复合材料。该复合材料具有三维贯通的多孔结构，以亚纳米尺度
