In this work, the influence of Ce and Mo promoters on the properties of Fe–Ni/TiO₂–Al₂O₃, Fe–Ni–Ce/TiO₂–Al₂O₃, and Fe–Mo–Ce/TiO₂–Al₂O₃ catalysts was investigated in CMD reactions under dry conditions and in the presence of steam at 600–850 °C. Comprehensive characterization by XRD, H₂-TPR, TPO, Raman spectroscopy, and TGA revealed that CeO₂ enhances the reducibility and oxygen mobility of Fe-Ni phases, whereas Mo is present in the form of highly dispersed MoO_x species and significantly alters their redox properties. The Fe–Ni–Ce/TiO₂–Al₂O₃ catalyst exhibited the highest methane conversion (96% at 850 °C) together with superior time-on-stream stability, while Fe–Mo–Ce/TiO₂–Al₂O₃ demonstrated high initial activity but underwent faster deactivation due to the accumulation of highly graphitized coke. Correlation of Raman and TGA data with catalytic performance showed that CeO₂ promotes the formation of predominantly ordered sp² carbon structures and facilitates the gasification of defective carbon species, whereas Mo favors the growth of more thermally stable graphitized phases. Based on these findings, a coke formation mechanism is proposed in which the type and stability of carbon deposits are governed by the redox properties of the promoters and the presence of steam. These findings enable rational tuning of catalyst behavior of CMD catalyst operation toward either enhanced hydrogen production or the synthesis of highly graphitized carbon materials.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we investigate the influence of pyrolysis temperature (800–1100 °C) on Co–N/C catalysts derived from ZnCo-ZIF for the aerobic oxidation of 5‑hydroxymethylfurfural (HMF) to 2,5‑furandicarboxylic acid (FDCA). A volcano‑shaped dependence of FDCA yield on pyrolysis temperature is observed, with the catalyst pyrolyzed at 1000 °C (Co–N/C-1000) delivering complete HMF conversion and 98.0% FDCA yield within 4 h under optimized conditions (110 °C, 2 MPa O₂). Multi-technique characterization reveals a temperature-driven evolution of Co species: from atomically dispersed Co–N_x sites at 800–900 °C, to a bimodal configuration comprising abundant Co–N_x together with a small amount of metallic Co⁰ nanoparticles at 1000 °C, and finally to large Co aggregates at 1100 °C. The optimal catalytic performance at 1000 °C is thus attributed to this unique coexistence. Kinetic analysis confirms the consecutive pathway HMF → HMFCA → FFCA → FDCA with FFCA→FDCA as the rate‑determining step. Notably, the optimal catalyst maintains 96.8% FDCA yield under industrially relevant 5 wt% HMF concentration.

However, pristine Zn-based MOF (MOF-5) generally exhibits poor catalytic activity due to its wide band gap, limited visible-light absorption, and rapid recombination of photogenerated charge carriers. In this work, these limitations were addressed by amine functionalization and Fe₂O₃ nanoparticle incorporation, leading to the construction of a multifunctional Fe₂O₃@NH₂-MOF-5 heterostructured catalyst through a facile synthesis strategy. Structural and optical characterizations supported the successful formation of the composite and revealed enhanced visible-light absorption and a reduced band gap compared with pristine MOF-5. Electrochemical measurements showed that Fe₂O₃@NH₂-MOF-5/NF exhibited improved oxygen evolution reaction (OER) activity, requiring an overpotential of 230 mV at 10 mA cm⁻² with a Tafel slope of 58 mV dec⁻¹, together with enhanced hydrogen evolution reaction (HER) performance, delivering an overpotential of 94 mV at 10 mA cm⁻². Furthermore, the composite achieved 86% Rhodamine B (RhB) degradation within 60 min and a hydrogen evolution rate of 146.81 µmol g⁻¹ h⁻¹ under light irradiation. Based on the band structure analysis and photocatalytic performance, a proposed Z-scheme charge-transfer pathway provides a plausible explanation for the enhanced catalytic activity by facilitating charge separation while preserving strong redox capability. This work demonstrates that amine functionalization combined with Fe₂O₃ incorporation is an effective strategy to overcome the intrinsic limitations of MOF-5, enabling the development of efficient multifunctional catalysts for water splitting and environmental remediation.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
