模板法煤沥青基中孔炭的制备及其电化学性能
The electrochemical properties of templated and activated mesoporous carbons produced from coal pitch
摘要
Abstract
Mesoporous carbons ( MCs) were made from coal pitch derived from coal liquefaction residue with silica nanoparticles as template and CO2 as activation agent. The microstructure and electrochemical properties of the MCs were investigated with TEM, N2 adsorption, an electrochemical workstation and a Land battery test system. Results show that the specific surface area increases with activation time at 900 ℃ under a CO2 flow rate of 100 mL·min-1. The specific surface area of MC activated for 150min is 1360 m2·g-1 while that of the un-activated one is 722 m2·g-1. The specific capacitance of the MC activated for 150 min is 135 F·g-1 at a current density of 1 000 mA·g-1 and the decrease in its specific capacitance is 7％ after being charged and discharged 10000 times.关键词
