چکیده انگلیسی
A three-dimensional porous carbon skeleton with hexagonal channels was synthesized by using mollusc shell as the carbon source. The obtained mollusc shell based macroporous carbon material (MSBPC) has high conductivity and is very favorable for use in the electrolyte penetration and electron transfer, making it an excellent carbon substrate for composite electrode materials. After incorporation of MnO2 nanosheets, the MSBPC/MnO2 was synthesized and applied in supercapacitors, which exhibited a high specific capacitance of 386Â FÂ gâ1 at 1Â AÂ gâ1 with an excellent rate performance (278.7Â FÂ gâ1 at 10Â AÂ gâ1), and outstanding cycling stability, with a capacitance retention of 83% after 5000 cycles at 20Â AÂ gâ1. The good electrochemical performance indicates the high potential of the prepared MSBPC/MnO2 as a novel supercapacitor electrode material with a high power density, excellent long life cycling, and environmental friendliness.
