Photoelectrocatalytic CO₂ reduction, which synergistically integrates solar energy harvesting photocatalysis with the controllable effectiveness of electrocatalysis, has emerged as an optimistic pathway to transform CO₂ into valuable chemicals and fuels under mild conditions. This review methodically summarizes the fundamental principles, detailing critical steps from light absorption to surface redox reactions. The objective of this review is to comprehensively analyze current advances in Cu-based materials, which are uniquely positioned as catalysts due to their ability to facilitate multi-electron transfer and produce various hydrocarbons and oxygenates. We critically evaluate the performance of numerous Cu-based photoelectrodes and their hybrid nanostructures by benchmarking crucial parameters, like a faradaic efficiency of 63.3% for C₂ products and 47.4% for C₂₊ oxygenates. Additionally, the discussion summarizes future mechanistic pathways for significant products like HCOO^–, CH₄, and C₂H₄, correlating the local environmental and oxidation state of Cu active sites with experimental findings as well as a theoretical view. Despite substantial advancement, challenges such as poor product selectivity, competing hydrogen evolution, and limited long-term stability persist. This review also identifies tactical interventions, such as heteroatom doping, heterojunction formation, and application of a protective overlayer. Ultimately, this review provides future perspectives emphasizing the need for <i>in-situ/operando</i> characterization, rational design of tandem catalyst systems, and integration with scalable solar fuel production.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><img></picture></div></div></figure></div></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 17-18","pages":"2414 - 2442"},"PeriodicalIF":3.7,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099095","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}

Conventional catalysts based on Fe₃O₄ usually suffer from a number of disadvantages, including moderate activity, limited recyclability, and reduced stability in green reaction conditions. In this respect, a series of Mg²⁺-doped ferrites were prepared by an easy co-precipitation route to modulate the acid–base balance and surface properties. XRD, FTIR, FESEM, TEM, UV–Vis, and VSM characterized the obtained nanosized spinel MgFe₂O₄ with increased surface area and magnetic separability. Under MW irradiation, the MgFe₂O₄ catalyst displayed as high as 70% yield in 10 min and was more active than the corresponding undoped Fe₃O₄ counterpart. Moreover, this nanocatalyst showed regular behavior after five reuse cycles with a minimal loss in activity. 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. This article extensively discusses the multifaceted novel antiviral strategies and mechanisms of action of nanomaterials as novel antiviral agents for the attenuation of SARS-CoV-2 infections and pathogenesis using diverse mechanisms.

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.
