Introduction: The Averrhoa carambola extract was used as a capping and reducing agent to synthesize the CuCeO2 nanoparticles in an eco-friendly method. Materials and Methods: Techniques such as UV-Vis Spectroscopy, XRD, FESEM, EDX, HRTEM, FTIR, and BET were used to characterize the synthesized CuCeO2 nanoparticles. Results: A morphological analysis revealed that the green-synthesized CuCeO2 nanoparticles are spherical, mesopore, monoclinic, and have an average particle size of 14.87 nm. Discussion: The photocatalytic and antibacterial properties of the synthesized CuCeO2 nanoparticles were investigated. CuCeO2 nanoparticles were used to accomplish the complete degradation of the crystal violet dye, illustrating the efficacy of photocatalysts in environmental remediation. The clinical pathogens were tested for antibacterial effectiveness using the agar well method. The CuCeO2 nanoparticles showed strong antimicrobial activity against Gram-positive and Gram-negative bacterial strains of S. aureus, B. subtilis, and E. coli, P. aeruginosa, as well as fungal strains of Candida albicans, respectively. conclusion: These findings demonstrate the potent antimicrobial and photocatalytic characteristics of CuCeO₂ nanoparticles, indicating its potential as a promising material for environmentally remedial photocatalysts and sustainable antimicrobial treatments.
