Synthesis and Properties of Hierarchical Macro-mesoporous Carbon Materials: Synthesis and Properties of Hierarchical Macro-mesoporous Carbon Materials

Hierarchical macro-mesoporous carbon material (HMMC) was synthesized successfully via a facile dual-templating method using resols as carbon source, in which polystyrene (PS) colloid was selected as macro- porous template and Pluronic F127 as mesoporous template. After thermosetting treatment and carbonization step, HMMC can be obtained. The product was characterized by XRD, SEM, TEM and N2 adsorption techniques. The electrochemical performance of HMMC was evaluated by cyclic voltammetry and galvanostatic charge/discharge methods using an electrochemical workstation and a battery testing system. Results show that HMMC material has three-dimensional connected macroporous structure with pore size of 1μm and ordered mesoporous windows with average pore size of approximately 5nm. BET surface area of the product is 353.8m 2 /g and pore volume is 0.36cm 3 /g. The CV curves of HMMC are quasi-rectangular, the specific capacitance of product is calculated to be about 40F/g at a constant current density of 50mA/g. It is anticipated that these novel materials synthesized by the
