The invention relates to a method for preparing porous nano carbon materials with biomass serving as a carbon source, particularly to a method for preparing nano carbon materials with biomass fasciculus vascularis luffae serving as the carbon source, and solves the problems that methods for preparing existing nano carbon materials are complex in technological process and higher in preparation cost and the prepared nano carbon materials are low in specific surface area and poorer in stored energy. The preparation method comprises the steps as follows: I, pretreatment of the fasciculus vascularis luffae; II, activation and drying of the fasciculus vascularis luffae; III, heat treatment under inert gases; IV, treatment with an acid leaching method. Compared with the existing nano carbon materials, the porous nano carbon materials prepared with the biomass fasciculus vascularis luffae serving as the carbon source have the advantages that the specific surface area is significantly increased, and the materials have good electrochemical performance; the method is simple in experimental process, and large-scale industrial production can be realized by the aid of biological resources.
