Two biomass material-derived self-doped (N/O) porous carbons from waste coriander and lilac with high specific surface areas and high capacitance for supercapacitors

Abstract

In this study, two kinds of 3D self-doped (N/O) lilac-based and coriander-based porous carbons with high performance have been prepared.

MnO2 Nanoparticle‐Loaded Self‐Doped (N/O) Porous Carbon Derived from Orychophragmus Violaceus for Application as a High‐Performance Supercapacitor

“…[1][2][3] The performance of supercapacitors is bound up with the choice of electrode materials, which generally include metal compounds, conductive polymers and carbon materials, among which carbon materials include activated carbon (ACs), carbon nanotubes (CNTs), carbon fiber (CFs), graphene, etc. [4] ACs is an excellent electrode material for supercapacitors due to its abundant pore structure, higher specific surface area and low cost. [5] Carbon materials derived from biomass do not only offer low cost of preparation, diverse source and ease of preparation but also plays an important role in protecting the environment.…”

Investigating electrochemical behavior of cobalt pentacyano(methylaniline)ferrate(ii) in various aqueous electrolytes for supercapacitor application

“…However, the lower energy density of supercapacitors hinders their widespread commercial application. 6 According to the equation E = 1/2 CV 2 , specific capacity and operating potential window are two main factors in achieving higher energy density. Specific capacity strongly relies on designing electrode materials while operating potential windows can be enhanced by fabricating asymmetric devices rather than symmetric ones.…”
