This review provides a comprehensive overview of the cathode materials for CO2RR to CO in SOECs, with a particular focus on perovskite-based cathodes, their modification strategies, and recent research advances. The thermodynamic fundamentals of CO2 reduction and the mechanistic pathways of CO2 conversion on perovskite surfaces are summarized. Various perovskite cathode materials and their corresponding electrochemical performances achieved through different modification approaches are reviewed. Furthermore, the influence factors, including temperature, applied potential, CO2 feeding concentration, and electrode thickness, on SOEC performance highlighted in detail.

In this work, by introducing two CN in BT, the molecule 2,1,3-benzothiadiazole-4,7-dicarbonitrile (BTDN) has multiple reduced states as compared to BT and is found to interact with CO2 at multiple reduced states. The work is carried out with a combination of (spectro-)electrochemical and computational studies. Cyclic voltammetry experiments in the presence of CO2 show a clear interaction between BTDN and CO2 upon the second reduction of BTDN and a large current increase at the third reduction. Density functional theory calculations prove a large variety of possible CO2-bound species that can match the experimental data. The binding of CO2 on BTDN is found to be reversible upon the oxidation of the species, especially with low concentrations of CO2. From NMR and IR experiments, certain amount of reduced product - oxalate is detected after bulk electrolysis at the third reduction potential in the presence of CO2, showing the potential toward electrocatalysis after structural tuning and systematical optimization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501724"},"PeriodicalIF":6.6,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145297817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a formic acid-phenol-water system (FP) for achieving extreme delignification is developed, simultaneously producing high-purity/brightness cellulose pulp fiber and phenolated lignin directly from lignocellulosic biomass. The strategy allows to establish a competitive reaction mechanism by introducing active phenol to replace lignin fragments and to react preferentially with lignin-reactive intermediates, enhancing the lignin removal rate while avoiding its condensation. The directly produced cellulose pulp with superior purity enables it to be adapted to different application areas, e.g., dissolving pulp for textile. Importantly, the in situ phenolated lignin from FP fractionation possesses high reactivity and can be directly considered as bioadhesive for plywood production.

Comprehensive gene-expression-profiling revealed upregulation of phosphoenolpyruvate carboxylase (ppc/PPC) in CA and pyruvate carboxylase (pyc/PYC) in BS, reflecting intensified carboxylation activity via the reductive tricarboxylic acid pathway. Protein/structural modeling/docking of PPC and PYC demonstrated enhanced catalytic-site exposure under electro-fermentative co-culture conditions, correlating with greater carboxylation efficacy.

Thermodynamic and electrochemical evaluation indicated greater stability and electron flow in co-culture reactors (R9:ΔG = -42.29 kJ) compared to monocultures.

Major recycling routes such as pyrometallurgy and hydrometallurgy offer promising paths for metal recovery, but their efficiency often depends on the pretreatment of spent batteries. However, optimizing low-temperature pretreatment for complete organic removal while preserving active material integrity remains challenging. This study investigated thermal decomposition and surface changes of key battery components-lithium nickel manganese cobalt oxide (NMC622) cathode, graphite anode, and polymeric separator-from 100 to 800 °C, focusing on the 400-650 °C industrial interval. Material responses were characterized using thermo-gravimetric analysis coupled with mass spectrometry, isothermal mass loss, and scanning electron microscopy with energy-dispersive X-ray spectroscopy. A 500 °C treatment was identified as optimal, enabling complete organic carbon removal within 1 h without compromising the NMC spinel structure or current collector degradation. This precise control reduces energy consumption and mitigates hazardous gas release, enhancing environmental sustainability and providing a practical, scalable, and cost-effective strategy for improving battery recycling. These findings help to define the parameters for efficient electroactive material separation.
