This study employed <em>Syzygium malaccense</em> leaf extract as a reducing and stabilizing agent for synthesizing ZnO NPs. The ZnO NP was characterized by UV–Vis spectroscopy, FTIR, XRD, and SEM-EDX. UV–Vis spectroscopy revealed a strong absorption peak at 371 nm, corresponding to a bandgap energy of 3.23 eV, determined by Tauc’s plot. FTIR identified characteristic Zn–O, C-O, and C=C bonds at 574 cm⁻¹, 1188 cm⁻¹, and 1643 cm⁻¹, respectively. XRD analysis demonstrated the crystalline nature of ZnO with an average crystallite size of 25 nm and face-centred cubic (FCC) crystal structure. SEM-EDX provided insights into the surface morphology and elemental composition. The photocatalytic efficiency of ZnO NPs was evaluated on Neomycin (NEO) under UV light. The degradation reaction process followed a pseudo-first-order kinetic model with a reaction rate constant (<em>k</em>) value of 0.021 min⁻¹ and <em>R</em>² value of 0.87 (87 %). Additionally, ZnO NPs were incorporated into dye-sensitized solar cells (DSSCs) as a functional layer. Maximum solar-to-electric power conversion efficiency of 6.4 % was achieved by the DSSC fabricated using ZnONP photoanode, which also had an open-circuit voltage of 0.52 V, a short-circuit current of 54 mA/cm², and a fill factor of 0.57. The photovoltaic performance measurements demonstrated promising power conversion efficiency. This study affirms the dual purpose of <em>Syzygium malaccense</em> leaf extract-mediated ZnO NPs for UV-assisted photodegradation of NEO in wastewater and as a photoanode in DSSCs.These findings underscore the multifunctionality of the synthesized nanomaterial for environmental remediation purposes and solar energy harvesting.</div></div>","PeriodicalId":18233,"journal":{"name":"Materials Science and Engineering: B","volume":"319 ","pages":"Article 118324"},"PeriodicalIF":3.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observed enhancement of the dielectric constant with temperature and its reduction with frequency can be revealed by applying the Maxwell–Wagner relaxation model. The dielectric loss study shows that the material possesses the Arhenious relaxation behavior. From the Arrhenius equation, we have found the activation energy of the material whose values are nearly close to each other. From the impedance spectroscopy studies, we have observed that the material possesses the contribution of both the grains and the grain boundaries, where grains are observed at lower frequencies and the grain boundaries are at higher frequencies. Our observations reveal that all modulus curves converge at low temperatures, demonstrating a similar relaxation pattern, while the curves at high temperatures display a dispersed behavior beyond the peak frequency. The observed AC conductivity adheres to Jonscher’s power law, suggesting that the synthesized material exhibits semiconducting characteristics. Additionally, the temperature-dependent components indicate that the material aligns with the non-overlapping polaron hopping and carrier barrier hopping models, which are the most suitable frameworks for elucidating the conduction mechanism of the samples.
