In-situ template cooperated with urea to construct pectin-derived hierarchical porous carbon with optimized pore structure for supercapacitor

Oxygen and nitrogen enriched pectin-derived micro-meso porous carbon for CO2 uptake

“… 31 Pectin can be produced in a gel-like structure, and this gel might provide access to novel carbonaceous materials with unique porosity properties. 32 Pectin has been effectively used as a functional biopolymer to create N/O co-doped 3D carbon architecture with hierarchical pores for supercapacitor by Zhou et al 33 As well as Zhang et al using pectin as the porous carbon precursor, an adsorbent for methylene blue was gained. 31 Further, Yuanyuan et al synthesized pectin-derived N, S-enriched carbon to enhance the charge transfer and oxygen reduction reaction (ORR) electrocatalysts activity.…”

B, O and N Codoped Biomass-Derived Hierarchical Porous Carbon for High-Performance Electrochemical Energy Storage

“…The power density P cell (W kg −1 ) and energy density E cell (W h kg −1 ) of symmetric SC were calculated according to the following equation [ 26 , 27 ]: where ∆ t (s) is the discharge time and ∆ V (V) is the discharge voltage range.…”

Hierarchical porous carbon derived from coal tar pitch by one step carbonization and activation combined with a CaO template for supercapacitors

“…6(b)-(f), and all the N 1s spectra can be decomposed into three peaks located at around 401.0-401.9 eV, 399.9-400.3 eV and 398.6-399.0 eV corresponding to graphitic-N (N-Q), pyrrolic-N (N-5) and pyridinic-N (N-6), respectively. 37,38 Meanwhile, it can be noted from the relative content of different types of nitrogen in Fig. S3(a) (ESI †) that pyrrolic-N (N-5) is predominant for the HPC samples, and a large number of N-5 can serve as the active species to further provide additional pseudocapacitance in alkaline electrolytes.…”
