Metal–organic frameworks (MOFs) have emerged as a versatile platform for eCO2RR catalyst design, owing to their high surface areas, atomically tunable active sites, chemically functionalizable pore environments, and well-defined structures. Herein, recent advances in MOF-based electrocatalysts for selective CO2 reduction are comprehensively summarized, with the discussion organized according to target product scope to reflect the distinct catalytic requirements of each reaction pathway. For C1 products (CO, CH4, HCOOH), we discuss how ligand engineering, bimetallic synergy, and microenvironment modulation have been deployed to meet the distinct catalytic requirements of each pathway. For C2+ products (ethylene, ethanol), we analyze strategies for enabling C─C coupling and controlling post-coupling hydrogenation pathways, including reconstruction guidance, tandem catalysis, and secondary coordination sphere engineering.

This review article develops a comparative framework that links structural polymorphism, kinetic and stoichiometric control, and photophysical loss pathways to the observed efficiency gap and scalability limits. We show that CIS performance is capped by deep traps originating from Cu/In imbalance, high-temperature kinetics, and parasitic phases, which enforce trap-limited transport and large VOC deficits.

The conductive mechanism changed from hopping conduction to metal-like conduction as the CS content increased in the composites, which was caused by the formation of a three-dimensional conductive network. In addition, the negative permittivity was exhibited in the composites owing to the low-frequency plasma state of the free electrons in the CS-conduction network. The absolute values of negative permittivity increased with the increase of CS content, which was consistent with the Drude model.

Temperature distribution within the cell serves as a key diagnostic indicator, as localized hotspots accelerate degradation of cell components. In this study, a long short-term memory (LSTM) model is developed for predicting spatial temperature distributions in PEM fuel cells using readily measurable operating parameters and current distribution data. A 500-h experimental dataset under the new European driving cycle is employed, comprising 72 input features (24 operating parameters and 48 current sensors) and 48 temperature sensor outputs across a 50 cm2 active area. Bayesian optimization is applied for hyperparameter tuning, yielding an LSTM configuration that achieves high predictive accuracy (R2 > 0.91) when trained on only 100 h (20%) of the dataset under the investigated hyperparameter settings. Sensor-wise evaluation shows minimal error for central regions with uniform heat transfer, while higher deviations occur near edges due to local non-uniformities. This suggests the need for targeted calibration and feature engineering for edge regions to further enhance predictive reliability. Overall, the framework demonstrates a computationally efficient, data-driven pathway for predictive monitoring and diagnostics in PEM fuel cells.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 7","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.70573","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148467398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural and surface characterizations conducted provided compelling evidence that moderate Fe incorporation fosters partial graphitization, retention of nitrogen from the MOF precursor, and the establishment of conductive graphitic domains without significant pore obstruction. Electrochemical assessments performed in a 1 M KOH electrolyte employing cyclic voltammetry, galvanostatic charge-discharge and EIS techniques demonstrated that the Fe-modified electrodes exhibit a predominance of electric double-layer capacitance behavior, coupled with improved charge storage capacity and rate performance.
