As a key intermediate in pharmaceutical manufacturing and fine chemical production, pyrrolidine synthesis poses significant challenges in terms of efficiency. In this work, MgO was synthesized via the calcination of Mg(OH)₂, followed by the deposition of Ru onto MgO- 400 °C through a sodium borohydride reduction approach to produce the 1%Ru-MgO- 400 °C catalyst. The catalyst demonstrated exceptional performance under conditions of 170 °C and 3.5 MPa H₂ pressure, achieving complete conversion of pyrrole and a 100% yield of pyrrolidine. Advanced characterization methods such as XRD, TG, BET, SEM and HR-TEM were used to analyze the catalyst, revealing that the ruthenium nanoparticles were uniformly loaded on the MgO carrier to form a highly dispersed active site, while the crystal structure of MgO remained intact with excellent thermal stability, providing a structural basis for the efficient performance of the catalyst. Additionally, the catalyst exhibited remarkable stability and retained high activity over multiple reaction cycles, highlighting its suitability for industrial-scale applications. The findings of this study contribute novel perspectives to the development of robust and efficient hydrogenation catalysts and present a sustainable approach for the environmentally friendly synthesis of pyrrolidine.</p><h3>Graphic Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830872","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}

This paper introduces a scalable and efficient system for the selective photocatalytic conversion of liquid formic acid into hydrogen, under visible light. Formic acid decomposition can initiate two reactions. The first, called dehydration, results in the formation of carbon monoxide and water. The second, called dehydrogenation, results in the formation of carbon dioxide and hydrogen. In the present work, spinel ferrites (MFe₂O₄: M = Cu, Ni, Zn, and Co) are used as photocatalysts to selectively drive the dehydrogenation reaction to produce hydrogen. These catalysts were synthesized via a starch mediated auto-combustion solgel method, yielding crystallite sizes between 47 and 112 nm. Their structural, morphological, and optical properties are determined, including the band gap values ranging from 1.6 to 2.2 eV. The photocatalytic dehydrogenation process was monitored in real time using Fourier transform infrared spectroscopy (FTIR). This analysis revealed a dehydrogenation selectivity across all spinel ferrite samples but with varied amounts of the released CO₂. The highest amounts of CO₂ released after 10 h, both in the dark and under illumination, were observed for NiFe₂O₄ and ZnFe₂O₄. NiFe₂O₄ exhibits superior performance under dark conditions, while ZnFe₂O₄ demonstrates a more important activity under light irradiation. The results demonstrate that NiFe₂O₄ and ZnFe₂O₄ exhibit CO₂ production rates 3 to 4 times higher than those of CoFe₂O₄ and CuFe₂O₄ under light condition, highlighting the potential of these spinel ferrites as efficient photocatalysts for the dehydrogenation of formic acid.</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":"155 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769840","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}
