Herein, present an environmentally benign and novel approach for the synthesis of N/S-O<sub>x</sub> carbon material derived from natural polymers on gram scale. By capitalizing the synergistic effect of sulfonated lignin and amino-containing chitosan, this methodology produces a straightforward, low-budget, and scalable process. The incorporation of sulfonate motifs from lignin contributes to the formation of C-SO<sub>x</sub> moieties and multi-porous architecture with a high surface area. Simultaneously, amino groups in chitosan induce nitrogen doping, enhancing conductivity, and wettability. The resulting N/SO<sub>x</sub> carbon material exhibits a micro/meso-porous architecture, facilitating electrolyte diffusion, and demonstrating improved rate capability and pseudocapacitance via Faradaic redox reactions. The N/SO<sub>x</sub> carbon material showcases notable capacitance (392 F g<sup>−1</sup> at 1 Ag<sup>−1</sup>) as compared with the reported carbon materials form biomass and outstanding cyclic stability (94.8% retention after 5000 cycles). By optimizing various chitosan mass ratios, the most effective N/SO<sub>x</sub> carbon material SNACM = S/N-doped activated carbon material (SNACM-2) was produced using a lignin: chitosan sample ratio of 1:2 for symmetric supercapacitors. Furthermore, the quasi-solid-state symmetric supercapacitors based on SNACM-2 exhibit an excellent specific capacitance of 142 F g<sup>−1</sup> at 1 A g<sup>−1</sup>, coupled with outstanding flexibility. The SNACM-2 demonstrates a high-energy density of 9.8 W h kg<sup>−1</sup> at a power density of 0.5 kW kg<sup>−1</sup>.

Finally, we highlight some of the key challenges and future research directions in the development of porous metal chalcogenides as effective and efficient materials for environmental remediation and sustainable energy generation.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":93174,"journal":{"name":"EcoMat","volume":"5 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eom2.12419","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
