“…This loop hysteresis distortion occurred owing to the presence of ink‐bottled shaped and numerous narrow neck pores. This thin nature hinders N 2 gas desorption because of pore constriction, 55 although ZnCl 2 chemical impregnation (0.5 to 0.9 mol L –1 ) successfully enlarged the specific surface area to 495.08 m 2 g −1 (CP‐0.5), 632.19 m 2 g −1 (CP‐0.7) and 759.81 m 2 g −1 (CP‐0.9). This manifestation clearly proves that ZnCl 2 is a potential material for improving surface area and increasing the amount of pores, which is necessary in the creation of more active sites for ion diffusion at the electrode–electrolyte interface.…”

BACKGROUND Agro‐industrial co‐products rich in lignocellulose, for example cassava petiole (CP) waste, have high potential as sources of porous carbon materials, alongside other impressive advantages, including ease of acquisition, abundance and availability, renewability and low cost. This work shows the successful treatment of mesoporous carbon with rod‐like structure derived from agro‐industrial CP waste carbonized and physically activated by direct one‐stage integrated pyrolysis using a zinc chloride (ZnCl2) activator agent, in the production of a supercapacitor electrode for energy storage. The ZnCl2 was tested at varying concentrations, including 0.5, 0.7 and 0.9 mol L–1. The surface morphology, chemical content, surface area and porous size distribution were evaluated to determine the physical properties of activated carbon, and a cyclic voltammetry method was used to assess the electrochemical characteristics using a two‐electrode system in 1 mol L–1 H2SO4 as an electrolyte. RESULTS The porous carbon obtained displayed a rod‐like morphology structure, featuring numerous hierarchical tuneable and well‐confirmed micropores and mesopores. This monolithic material contained predominantly C (87.85%), demonstrating a maximum surface area of 759.816 m2 g−1 at 0.9 mol L–1 concentration. Furthermore, the highest specific capacitance reached was 193 F g−1 at 0.7 mol L–1, with maximum energy and power densities of 26.90 Wh kg−1 and 96.94 W kg−1, respectively. CONCLUSION The novel rod‐like mesoporous carbon derived from CP waste produced using a facile, cost‐effective and sustainable method, without metal–organic framework or templates, shows great potential as an electrode material for enhanced supercapacitor performance. © 2020 Society of Chemical Industry (SCI)

A suitable electrode or active material is one of the promising ways to boost supercapacitors' efficiency. The right properties of the electrode materials will enhance the performance of the supercapacitors. New electrode materials such as biomass-derived carbon, mesoporous materials, and transition metal nitrides have been studied as potential substitutes for the most common electrode material, activated carbon. This review discusses the recent (5 years) progress of the electrode materials in supercapacitors compiling the literature from 2016 to 2020. The overview of design (structures), recent developments, and challenges of the new electrode materials are presented in this review with considerations on their electrochemical performance in supercapacitors.

Microporous activated carbon (MAC) was synthesized from winemaking waste and was used to adsorb Mn(VII) from aqueous solutions under various experimental conditions. Moreover, Mn(VII) adsorption on MAC was compared to other adsorbents and an ion-exchange resin, as well as those of other anionic complexes. Langmuir type-1 isotherm best fitted the adsorption process, whereas for all the studied temperatures (30 C-60 C), the experimental data fitted well with the pseudo-second-order kinetic model. The calculated activation energy was 8.1 kJ Á mol −1 , suggesting that Mn(VII) adsorption onto the MAC was a physical adsorption driven process. A reduction of Mn(VII) to Mn(II) occurs at a pH of 1 with the precipitation of MnO 2. Mn(VII) recovery from loaded-activated carbon using acidic conditions and different variables was investigated.
