Surface modification of nanoporous materials for electric double layer capacitors application

A facile and green preparation of durian shell-derived carbon electrodes for electrochemical double-layer capacitors

“…This result may confirm the synergistic effects between microporosity and carbon surface chemistry in improving the electrochemical performance of electrodes. Similar results were also found in several works [16,29,30]. The electrodes prepared from AC-313.15/20/900/8 and AC-323.15/10/900/10 carbons (Fig.…”

Sustainable synthesis of phosphorus- and nitrogen-co-doped porous carbons with tunable surface properties for supercapacitors

“…Another approach to prepare heteroatomincorporated carbons is post treatment of a porous carbon, including surface oxidation, phosphoric acid activation [18,25], ammonia oxidation [26,27], or plasma treatment [28]. Recently, techniques and processes involved in the synthesis of heteroatom enriched porous carbon materials derivate from sustainable precursors have attracted growing interest due to their low cost, energy and atom economy, and low toxicological impact of processes and materials themselves [29].…”

“…The encountered problem lies in not only the complexity of the carbon surfaces but also the diversified development pathway of the heteroatom-containing surface groups [11,14,18,33,34,38e40]. Post-synthesis approach seems to be one practical way for the preparation of porous carbons with tunable surface properties, but this approach is costly, tedious and time-consuming [14,27,28,40,41].…”

Preparation of capacitor’s electrode from cassava peel waste

“…Activated carbon is a suitable material for the production of electrode for supercapacitors, because of its high surface area, good thermal and electric conductivity, good anti-causticity, high stability, low cost, and commercially available (Yafei et al, 2008). The application of activated carbons and other carbonaceous materials as the electrode of EDLCs has been studied by various research groups (Centeno and Stoeckli, 2006;Chmiola et al, 2006;Feng-Chin et al, 2006;Frackowiak and Beguin, 2001;Kim et al, 2006;Morishita et al, 2006;Tamai et al, 2005;Tashima et al, 2007;Xu et al, 2008;Yafei et al, 2008;Yansu et al, 2008).…”
