A range of Co–Mo@PVDF-HFP nanofibrous membranes, differing in Mo loading (0–0.5 Mo), were synthesized by electrospinning, followed by in situ NaBH₄ reduction. SEM–EDX mapping validated the uniform co-localization of Co and Mo within the NFs matrix. Furthermore, XRD analysis showed no crystalline metal phases, suggesting the formation of amorphous or ultrafine Co–Mo domains within the polymer network. The 0.3 Mo@PVDF-HFP catalyst demonstrated the highest hydrogen generation rate of 70.22 mol H₂ min⁻¹ g⁻¹Co at 298 K, which is a 2.6-fold improvement compared to monometallic Co. Kinetic studies revealed a near-first-order relationship with respect to both catalyst loading and AB concentration, accompanied by an apparent activation energy of 19.21 kJ mol⁻¹. The catalyst retained ~ 80% of its initial activity after six cycles. This enhanced performance is ascribed to robust Co–Mo electronic synergy, the presence of amorphous bimetallic active sites, and the piezoelectric polarization of PVDF-HFP induced by stirring; these factors collectively facilitate interfacial charge enrichment, expedite interfacial electron transfer, and mitigate nanoparticles (NPs) migration. Consequently, this research presents a scalable approach for developing flexible, piezo-assisted, polymer-confined bimetallic catalysts, thereby enabling efficient, on-demand H₂ production.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>Fabrication of piezoelectric Co–Mo@PVDF-HFP nanofibers and their application as efficient catalysts for hydrogen production from ammonia borane methanolysis.</p></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927135","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}

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}
