Unavoidable complicated oxygen functionalities in porous carbons restrict identification of their electrochemically active sites. Herein, we report 3D interconnected macroporous/microporous catechol-enriched carbon through first-step low-temperature pyrolysis and second-step melted KOH etching resorcinol-formaldehyde resin its excellent pseudocapacitance. First, high-content hydroxyl groups a carbonaceous framework stem from preservation after introduction treatment. Second, molten removes...
An air-breathing chemical self-charge concept of oxygen-enriched carbon cathode. The material with abundant catechol groups. Rapid air-oxidation self-charging has drawn considerable attention due to its excellent ability achieve environmental energy harvesting, conversion and storage without an external power supply. However, most designs assembled by multiple materials increase the transfer loss; supply is generally limited climate meteorological conditions, hindering potential application...
Abstract Herein, we report an effective strategy to synthesise a hierarchically porous pyrrolic nitrogen‐dominated doped carbon material (N‐doped material) by the low‐temperature carbonisation and post‐KOH activation of 3‐fluorophenol‐3‐aminophenol‐formaldehyde co‐condensed resin using self‐sacrificial SBA‐15 template. Low‐temperature thermal treatment successfully prevented transformation thermally unstable pseudocapacitance‐active nitrogen pseudocapacitance‐inactive graphitic...
