Abstract: Hierarchical macro-mesoporous carbon material (HMMC)was synthesized successfully <>via a facile dual-templating method usingresols as carbon source, in which polystyrene (PS) colloid was selected as macroporoustemplate and Pluronic F127 as mesoporous template. After thermosettingtreatment and carbonization step, HMMC can be obtained. The product was characterizedby XRD, SEM, TEM and N₂ adsorption techniques. The electrochemical performanceof HMMC was evaluated by cyclic voltammetry and galvanostatic charge/dischargemethods using an electrochemical workstation and a battery testing system. Resultsshow that HMMC material has three-dimensional connected macroporous structurewith pore size of 1μm andordered mesoporous windows with average pore size of approximately 5nm. BET surface area of the product is 353.8 m²/gand pore volume is 0.36cm³/g. TheCV curves of HMMC are quasi-rectangular, the specific capacitance of product iscalculated to be about 40F/g at a constant current density of 50mA/g. It isanticipated that these novel materials synthesized by the simple methods havepotential applications in electrode materials.
