The invention relates to a porous nano-gold carbon nanotube composite material and a preparation method thereof. The porous nano-gold carbon nanotube composite material is characterized in that nano-gold particles with large size are accumulated to form a tunnel, the carbon nanotube is interpenetrated in the tunnel, and nano-gold particles with small size is attached on the surface of the carbon nanotube. The nano-gold carbon nanotube composite material with the porous structure is obtained by crystallization of nano-gold seed crystal with the crystal grain size of 20-30 nm by taking toluene as a solvent through a solvothermal method. Compared with the traditional porous gold material, the method provided by the invention use a self-assembly solvothermal method, does not use a strong corrosive substance, reaction condition is mild, steps are simple, and the used reagent is mild. 本发明涉及种多孔纳米金碳纳米管复合材料及其制备方法。种多孔纳米金碳纳米管复合材料，其特征在于：大尺寸的纳米金颗粒堆积形成孔道，碳纳米管穿插其中，小尺寸的纳米金颗粒附着于碳纳米管的表面。所述的多孔结构的纳米金碳纳米管复合材料是将自组装法得到的晶粒尺寸为20-30nm
