Summary: | Unique synthesis method of protonating histidine with different inorganic acids is proposed as a novel efficient way to control the structural and surface properties of resulting carbon materials and eventually their electrochemical performance.
[Display omitted]
•Structural and electrochemical properties of carbon materials (CMs) is tuned by protonating histidine using different inorganic acids (HAs).•The effects of each HA on the structural properties of respective (HA)His-CM and on its electrochemical behaviors are investigated.•(H3PO4)His-CM possesses high specific surface area, high capacitance, superior energy density and power density along with excellent cycle life.•H3PO4 plays dual roles of in-situ activation and additional P doping in the carbon skeleton.•A strategy of acid treatment of histidine and in-situ activation is unique and favorable for scalable production of novel carbon materials.
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, HNO3, H2SO4, and H3PO4. In particular, the (H3PO4)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 (H3PO4)His-CM is attributed to the tunable structural properties of the precursor, where H3PO4 plays dual roles of in-situ activation and additional P doping in the carbon skeleton. |
