Currently, a main challenge is the poor stability of Cu catalysts under harsh reaction conditions due to metallic Cu sintering and agglomeration. Herein, a series of Cu_xFe_y/Al₂O₃ nanocomposite catalysts was prepared via controlled solution combustion synthesis (SCS) owing to its minimal reaction time and energy requirements that reduce Cu agglomeration. Among them, the Cu₅Fe₃/Al₂O₃ catalyst exhibited the most favorable structure with the smallest grain size of 2.09 nm, highest dispersion of 63.6%, and an optimal Cu⁺/Cu⁰ ratio of 1.0 than the traditional Cu/Al₂O₃ counterpart. The synergy between Fe₂O₃ and Cu inhibited the thorough reduction of Cu²⁺ to Cu⁰ and consequently facilitated H₂ dissociation and activation as well as the highly efficient activation of the ethyl levulinate’s (EL) carbonyl group. Unlike the traditional Cu/Al₂O₃ catalyst, for which activity rapidly decreased from 97% to 11% over 200 h, the Cu₅Fe₃/Al₂O₃ catalyst exhibited a high GVL yield of 85% and maintained excellent stability, attributable to the strong interaction between Cu nanoparticles and Al₂O₃ support as well as the confinement effect with barrier property of Fe doping. Therefore, the inexpensive, efficient, and stable Cu₅Fe₃/Al₂O₃ catalyst has potential applications in the selective hydrogenation of biomass-derived platform compounds.</p><p>Solution combustion synthesis was employed to prepare a Cu–Fe/Al₂O₃ nanocomposite catalyst, which exhibited excellent catalytic performance in the hydrogenation of biomass-derived ethyl levulinate to γ-valerolactone (GVL). This catalyst surpassed the performance of the traditional Cu/Al₂O₃ catalyst, particularly in terms of demonstrating a high GVL yield of 85% and maintaining stability for over 200 h. This excellent performance could be attributed to its high Cu dispersion, small grain size, and optimal Cu⁺/Cu⁰ ratio.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 4-7","pages":"1089 - 1101"},"PeriodicalIF":3.0,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work thus shows that Mg doping effectively enhances ferrite catalytic efficiency through electronic modification and provides a viable route for fast C–C bond formation under mild, green conditions.</p></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 8-11","pages":"1239 - 1251"},"PeriodicalIF":3.0,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several vaccines and antiviral medications have been developed, their efficacy has become limited due to the emergence of new SARS-CoV-2 strains (&gt; 4000 variants) hindering their prompt deployment. Hence, it is necessary to develop safe and potent antiviral drugs, which is the need of the hour. Recently the applications of nanomaterials (NMs) have revolutionized medical approaches toward the diagnosis and treatment of SARS-CoV-2. The compendium of potent antiviral nanostructures was accumulated from various public databases including PubMed, ScienceDirect, Google Scholar, and ResearchGate.

Using a straightforward co-precipitation technique, we synthesized a new copper-doped cobalt ferrite composite with sulfur-doped graphitic carbon nitride (Cu@CoFe₂O₄/S-g-C₃N₄) heterojunction nanocomposite in this work. The composite was systematically characterized using XRD, FTIR, BET surface area analysis, SEM, TEM, UV-Vis DRS, and PL spectroscopy to reveal its structural and optical properties. BET analysis confirmed a surface area of 85.4 m²/g, contributing to improved photocatalytic action. The photocatalytic efficiency was assessed using methylene blue (MB) as a model pollutant under solar radiation. Among the synthesized materials, the optimized Cu@CoFe₂O₄/S-g-C₃N₄ NC demonstrated outstanding performance, achieving 97% degradation of MB within 120 min, with a degradation rate constant of 0.032 min⁻¹, approximately 3.5 times higher than pristine g-C₃N₄ (0.009 min⁻¹) and 2.8 times higher than Cu@CoFe₂O₄ (0.011 min⁻¹). The effective charge carrier separation made possible by the heterojunction interface and the enhanced light absorption brought about by the combined effects of Cu doping and the integration of CoFe₂O₄ and S-g-C₃N₄ are responsible for this astonishing improvement. Stability and reusability tests confirmed the Nanocomposite retained 91.6% of its photocatalytic efficiency after five cycles, highlighting its robustness and potential for long-term application. The cost-effectiveness, environmental compatibility, and scalability of the Cu@CoFe₂O₄ /S-g-C₃N₄ make it a favorable intranet for industrial wastewater treatment. The highest antifungal activities of Cu@CoFe₂O₄ /S-g-C₃N₄ were estimated to be 36.7 mm, 39.4 mm, and 43.3 mm versus <i>C. gloeosporioides</i>,<i> E. salmonicolor and C. albicans</i>, respectively. This study underscores the potential of heterojunction-based photocatalysts in sustainable water purification, providing a pathway for tackling organic dye pollution. Future research will focus on extending this approach to address other emerging organic contaminants, further advancing global efforts in environmental remediation.</p></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 8-11","pages":"1200 - 1215"},"PeriodicalIF":3.0,"publicationDate":"2025-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
