Hard template-salt template double template preparation of heteroatom-doped hierarchical porous carbon and its electrochemical properties.

ABSTRACT: Heteroatom-doped hierarchical porous carbon (AF-MMTC) was prepared with hard template and salt template dual templating agents, and the effects of salt template additions on its micro-morphology, pore structure, specific surface area and electrochemical properties were investigated. The salt template not only acts as a template, but also plays the role of a pore-making agent. AF-MMTC5 has a high specific surface area of 1772 m² g^-1, a 41% microporous content and 1.8 at% nitrogen content. The electrochemical test results show that the specific capacitance of AF-MMTC5 is 231.9 F g^-1 (0.5 A g^-1) in the three-electrode system, and the capacity retention can reach 98.5% after 5000 cycles; in the two-electrode system, the specific capacitance of AF-MMT
