Developing low-cost, metal-based photocatalysts and antimicrobial materials with high effectiveness remains a major challenge. Therefore, it is crucial to design affordable nanocomposite materials that exhibit enhanced photocatalytic performance along with strong biocompatibility. Nanocomposites have emerged as promising candidates for producing safe and highly effective antibacterial materials. Recent research has extensively explored the individual photocatalytic and antibacterial properties of zinc oxide (ZnO) and graphene oxide (GO) nanomaterials. Building on this foundation, the present study focuses on the ultrasonic-assisted low-cost synthesis of ZnO-GO nanocomposites and their evaluation in photocatalytic and antibacterial applications. Characterization techniques confirmed the successful synthesis of the nanocomposites. X-ray diffraction (XRD) analysis revealed that the synthesized ZnO and GO were free from impurities and unwanted secondary phases. The average crystallite size using Debye Scherrer is 35nm and the average length of the nanoparticle using ImageJ software is about 45 nm. The determined lattice parameters A and C values are 0.3257 nm and 0.5220 nm respectively. Fourier-transform infrared (FTIR) spectroscopy confirmed the presence of characteristic absorption peak of the Zn-O bond stretching vibrational modes at 447 cm<sup>−1</sup> and bending vibrational modes corresponding to ZnO-GO bonds, alkoxy groups (O-H), epoxy groups (C-O-C), and carboxyl groups (C-O), indicating proper functionalization. UV–Visible spectroscopy showed an absorption peak of ZnO-GO nanocomposite at 372 nm and the band gap using Tauc plot is about 3.05 eV. Field emission scanning electron microscopy (FESEM) images demonstrated that ZnO nanoparticles were uniformly distributed over the GO sheets, indicating effective integration. In the photocatalytic test ZnO-GO nanocomposite degraded 98.73 % ± 0.68 % MB dye in 60 min. The antibacterial activity of the synthesized ZnO-GO nanocomposite was assessed against <em>Escherichia coli</em> (Gram-negative) and <em>Staphylococcus aureus</em> (Gram-positive) bacteria. The results revealed that the ZnO-GO nanocomposite exhibited significant antibacterial activity with mean inhibition zone value of 11.5 mm and 13 mm respectively against <em>Staphylococcus aureus</em> and <em>Escherichia coli</em>, highlighting its potential as a multifunctional material for environmental remediation and biomedical applications.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"57 ","pages":"Article 102457"},"PeriodicalIF":6.5,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144099688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
