This work elucidates the preparation of cost-effective and easily scalable polyacrylonitrile (PAN) electrospun nanofibers (NFs) as support for ZnO nanorods (NRs) photocatalysts. Then, Ag nanoparticles (NPs) were homogenously deposited on ZnO NRs/PAN NFs to prepare Ag NPs/ZnO NRs/PAN NFs samples. Photochemical and electrochemical characterization demonstrated a higher photocurrent density and stability for the Ag NPs/ZnO NRs/PAN NFs than ZnO NRs/PAN NFs. In addition, the prepared photocatalysts were utilized for the photodegradation of various dyes, including methylene blue (MB) and rhodamine B (RhB), as well as tetracycline (TC), an antibiotic serving as a model organic pollutant, under different light illumination conditions. The Ag NPs/ZnO NRs/PAN NFs demonstrated 2.4, 2.6, and 1.6 times higher photocatalytic activity than ZnO NRs/PAN for MB, RhB, and TC photodegradation under UV light, respectively. This floating and free-standing mat, with high stability, demonstrated 82% MB removal after 1 h of exposure to outdoor natural light. Mechanistic studies conducted by adding scavengers revealed that generating hot plasmonic electrons on the Ag NPs through illumination plays a pivotal role in improving the photodegradation activity of Ag NPs/ZnO NRs/PAN NFs mats. Furthermore, ultrasonic vibration was also utilized to induce piezoelectricity in the ternary Ag NPs/ZnO NRs/PAN NFs, resulting in an approximately 2.2-fold improvement in the MB photodegradation rate due to the synergistic effects of piezoelectricity and plasmonics. This durable and reusable photocatalyst, with its mechanical robustness and superior self-cleaning characteristics, is a promising system that offers a potential direction for future research and efficient wastewater treatment.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":753,"journal":{"name":"Research on Chemical Intermediates","volume":"51 11","pages":"6487 - 6514"},"PeriodicalIF":3.5,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296718","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}

The synthesized nanocatalysts were characterized using XRD, FT-IR, FE-SEM, EDS, and UV–Vis techniques, and their activity was optimized for the <i>N</i>-formylation of aniline under solvent-free conditions at room temperature. A study of surface morphology revealed that we successfully prepared microspheres of α-Fe<sub>2</sub>O<sub>3</sub>, Ni–Fe<sub>2</sub>O<sub>3</sub>, Cu–Fe<sub>2</sub>O<sub>3</sub>, and Zn–Fe<sub>2</sub>O<sub>3</sub>. All forms doped represented higher catalytic activity compared to the pristine α-Fe<sub>2</sub>O<sub>3</sub>, due to a synergistic effect resulting from the presence of transition metals along with Fe. Among all the as-synthesized doped catalysts, Cu–Fe<sub>2</sub>O<sub>3</sub> showed the highest activity due to the greater electronegativity of Cu compared to that of Ni or Zn. Thus, Cu–Fe<sub>2</sub>O<sub>3</sub> nanocatalyst was selected for the chemoselective transformation of various amines to the corresponding formamides as a sole product (average reaction time: 14 min, average conversion: 90%, average TOF: 0.42 min<sup>–1</sup>). Finally, the catalyst could be reused for up to six runs without notable decrease in its activity.</p></div>","PeriodicalId":753,"journal":{"name":"Research on Chemical Intermediates","volume":"51 11","pages":"6185 - 6201"},"PeriodicalIF":3.5,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296524","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}
