Utilizing cold coprecipitation and one-pot hydrothermal methods, a range of CeO₂ and highly efficient photocatalytic AgI/CeO₂ composites were successfully prepared. These composites were, for the first time, applied to bamboo scrimber for antimicrobial research, significantly enhancing its antibacterial properties. Advanced characterization techniques such as XRD, SEM, TEM, and FT-IR were employed to analyze the prepared materials' structural characteristics systematically. Under visible light irradiation, the photocatalytic activity of AgI/CeO₂ composite catalysts with varying AgI loadings was evaluated using levofloxacin (LVF) as a model pollutant. The results indicated that the 20%AgI/CeO₂ composite exhibited a unique mesoporous structure, high specific surface area, and optimal photocatalytic degradation efficiency for LVF, achieving a degradation rate of up to 94.06%. Additionally, this composite significantly bolstered the antibacterial efficacy of the bamboo scriber under visible light conditions. It was securely anchored onto the surface of the bamboo scriber through a specific surface treatment process, forming a durable and practical antibacterial protective layer. In conclusion, AgI/CeO₂ composites demonstrate exceptional performance in both photocatalytic degradation and bamboo scrimber modification, making significant contributions to environmental protection and the development of green building materials.
