The green and efficient use of them is urgently needed. Cigarette butts are waste cellulose-based materials consisting of the outer packaging (cellulose) and the filter tip (cellulose acetate) that are good candidates to be resourcefully utilized. Herein, N,O co-doped hierarchical nanoporous biochars (CNPBs) with uniform morphology are readily prepared from cigarette butts via hydrothermal carbonization, coupled with pyrolysis activation. The hierarchical pore structure and surface properties of the prepared biochars could be expediently controlled by adjusting the activator ratio and activation temperatures. The optimal CNPB, which has a high specific surface area (2,133.5 m2 g−1), excellent microporosity, and oxygen-rich properties, is obtained at the activation temperature of 700 °C with a potassium hydroxide ratio of 4 (CNPB-700-4). CNPB-700-4 exhibits an energy storage capacity of up to 344.91 F g−1 at a current density of 1 A g−1. After 10,000 constant charge/discharge cycles at a current density of 10 A g−1, the capacity remains at 95.44%. The energy density and power density of the assembled CNPB-700-4//CNPB-700-4 symmetrical supercapacitors are 24.33 Wh kg−1 and 373.71 W kg−1, respectively, demonstrating the high commercial value of the prepared material.","PeriodicalId":11562,"journal":{"name":"Energy, Ecology and Environment","volume":"2 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.maxapress.com/data/article/opr/preview/pdf/een-0025-0016.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the correlation between their structural characteristics and the pyrolysis chemistry remains unclear. Herein, two kinds of common palm feedstocks, tagua nut and bodhi root, were taken to explore the structure and pyrolysis characteristics using different characterization and experimental methods. Thermogravimetry-infrared spectroscopy (TG-FTIR) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) were employed to systematically investigate the pyrolysis characteristics and product distribution of tagua nuts and bodhi roots. Notably, the two raw materials exhibited high mannan contents of 87.59% and 88.01%, respectively, which exerted a fundamental influence on their pyrolysis behavior. The TG-FTIR results demonstrated that the maximum weight loss temperatures of the two materials were 301 and 302 °C, respectively. Among the anhydrosugars in the pyrolysis products, the proportion of levomannosan (LM) exceeded 90%. In Py-GC/MS tests, the maximum LM yield from tagua nut was 11.2 wt% (at 600 °C), while that from bodhi root was 10.9 wt% (at 500 °C). During the lab-scale pyrolysis, the highest yields of the organic liquid products were 31.5 wt% and 29.5 wt% for the two feedstocks at 600 °C. In the liquid pyrolysis products, a maximum LM yield of 5.8 wt% and a maximum 5-hydroxymethylfurfural (5-HMF) yield of 2.0 wt% were obtained, with trace furfural (FF, 0.50 wt% for tagua nut, 0.61 wt% for bodhi root). Finally, the pyrolysis mechanism of the two materials, especially the formation of LM, was discussed. The present work lays a foundation for the production of important anhydrosugars from the mannan-rich biomass wastes.","PeriodicalId":11562,"journal":{"name":"Energy, Ecology and Environment","volume":"2 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.maxapress.com/data/article/opr/preview/pdf/een-0025-0020.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve these problems, a series of NiO/MgAl2-<italic>x</italic>Fe<italic>x</italic>O4 (0.50 ≤ <italic>x</italic> ≤ 2.00) catalysts were prepared for accomplishing low-temperature H2 generation from catalytic methane dissociation and alleviating catalyst invalidation through a carbon dioxide reduction strategy. Results indicate that a methane conversion of 91.03% and a hydrogen concentration of 91.21 vol% were achieved at 650 °C using NiO/MgAlFeO4. Long-term durability experiments were conducted under high-temperature and carbon-deposited conditions, and the NiO/MgAlFeO4 material still had highly satisfactory activity and stability after 20 cycles. It is revealed that the lattice distortions of Fe-O and Al-O in NiO/MgAl2-<italic>x</italic>Fe<italic>x</italic>O4 could be the dominant factor for boosted hydrogen generation from methane decomposition, synergistically promoting methane activation and dehydrogenation. These findings provide new implications for advanced catalyst design, which will substantially promote methane decomposition in a highly efficient manner.","PeriodicalId":11562,"journal":{"name":"Energy, Ecology and Environment","volume":"1 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147902264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
