Abstract
A unique and effective synthesis approach to tune the structural and electrochemical properties of carbon materials (CMs) is demonstrated by template-free one-step pyrolysis of protonated histidine (His) containing each of different inorganic acids (HAs) such as HI, HBr, HCl, HNO 3 , H 2 SO 4 , and H 3 PO 4 . In particular, the (H 3 PO 4 )His-CM possesses high specific surface area, high capacitance, superior energy density and power density along with excellent cycle life. Such excellent electrochemical performance of (H 3 PO 4 )His-CM is attributed to the tunable structural properties of the precursor, where H 3 PO 4 plays dual roles of in-situ activation and additional P doping in the carbon skeleton. © 2019 The Korean Society of Industrial and Engineering Chemistry
