In this research, lignin, which is selected due to its renewable and abundant nature compared to traditional carbon sources, was used as the precursor for producing lignin-derived carbon materials through a carbonization-activation process. The resulting porous carbon materials underwent rigorous characterization using SEM, BET, Raman, XRD and XPS to uncover their morphological and structural intricacies. This study delves into the influence of purified lignin (PL) and the type of activator on the microstructure and electrochemical properties of the porous carbon. Notably, the optimal product, achieved with a mass ratio of EL to KOH at 1:2 and activation temperature at 750 °C, emerges as an excellent electrode material for high-performance supercapacitors. This superior carbon material boasts a remarkable specific surface area of 2615.5 m<sup>2</sup> g<sup>−1</sup>, demonstrating an electrochemical capacitance up to 350 F/g at 1 A/g, which surpasses many existing carbon materials in performance. By harnessing raw materials sourced from agricultural byproducts, this study not only presents a cost-effective solution but also proposes a novel approach towards the high-value utilization of biomass wastes. The successful preparation of activated carbon with exceptional performance from these renewable resources paves the way for the development of low-cost, high-performance supercapacitors, contributing significantly to the advancement of sustainable energy storage systems.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"194 ","pages":"Article 107688"},"PeriodicalIF":5.8,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To increase BSG degradation, whole cells were submitted to a hydrolysis step and the resulting product underwent a BMP test after 72 h. Compared to control tests through commercial enzymatic pretreatment of BSG and no enzymes addition, the use of whole cells has substantially increased biomethane production, given that values of 226.87 ± 2.43 Nml/gVS were found at the end of 39 days of incubation. Data from pH variation and COD removal evidence such a great performance of BMP with whole cells. There was no pH variation during anaerobic digestion, thus favoring methanogenesis.
