To overcome the limitations of asynchronous heat transfer in traditional co-pyrolysis processes, a ternary molten carbonate system (Li<sub>2</sub>CO<sub>3</sub>–Na<sub>2</sub>CO<sub>3</sub>–K<sub>2</sub>CO<sub>3</sub>) was used as the reaction medium to study the effects of temperature (450–550 °C) and feedstock ratio (CS:PE = 3:1–1:3) on the co-pyrolysis products of corn stover (CS) and polyethylene (PE) plastic. The molten-salt environment facilitated synchronized decomposition of CS and PE plastic, effectively suppressing polycondensation and coking reactions while promoting hydrodeoxygenation of functional groups and C–O bond cleavage. Moreover, alkaline sites provided by alkali-metal cations catalyzed more complete secondary cracking and reforming of volatiles, resulting in an increase in gas production and a decrease in bio-oil and biochar production. Meanwhile, the fractions of H<sub>2</sub> and CO in the syngas were enriched, the hydrocarbon content in the pyrolysis bio-oil increased, and oxygenated compounds such as alcohols, aldehydes, and ketones were markedly reduced. Additionally, the templating and etching effects of the molten salt improved the structural ordering of the biochar, lowered its O/C ratio, and promoted a transition from microporous to mesoporous architecture.

Despite the intrinsic redox activity of CuBi<sub>2</sub>O<sub>4</sub>, its practical application is limited by low electrical conductivity and restricted surface area. To address these challenges, a porous AC matrix was introduced to enhance the electrochemical performance. Electrochemical measurements, including cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD), revealed that the CuBi<sub>2</sub>O<sub>4</sub>/AC composite exhibited a significantly enhanced specific capacitance of 228 F gg<sup>−1</sup> at 5 mV s<sup>−1</sup> and 170 F g<sup>−1</sup> at 1 A g<sup>−1</sup>, compared to 131 F g<sup>−1</sup> and 105 F g<sup>−1</sup> for pristine CuBi<sub>2</sub>O<sub>4</sub>. Electrochemical impedance spectroscopy (EIS) analysis indicated a lower charge-transfer resistance. These findings suggest that the CuBi<sub>2</sub>O<sub>4</sub>/AC composite is a promising candidate for sustainable supercapacitor electrode applications with improved electrochemical performance.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"211 ","pages":"Article 109223"},"PeriodicalIF":5.8,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387620","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}
