Abstract: A series of hierarchically structured nanoporous carbons are prepared via the direct carbonization of zeolitic imidazolate frameworks (ZIF-8) using a microwave-assisted heating method for the first time. The results indicate that the microwave carbonization temperature has a remarkable influence on the surface area and pore structure of the obtained porous carbons. ZIF-8 provides the carbon and the microporous structure. Significant numbers of mesopores and macropores emerge in the samples carbonized at high temperatures, indicating a clear difference from carbons prepared using traditional heating methods. The resulting porous carbons possess surface areas ranging from 384.4 to 947.5 m2 g-1 and pore volumes ranging from 0.17 to 0.49 cm3 g-1. For a carbonization temperature of 1000 °C, the porous carbon possesses the largest specific capacitance of 207.7 F g-1 at 0.1 A g-1 and the highest retention of 66.5% when the current density increases from 0.1 to 10 A g-1, which should be attr ibuted to the proper hierarchical pore structure and the relatively high graphitization degree.
