摘要:	In this study, we present a novel approach for the preparation of a highly ordered interconnected three-dimensional (3D) porous network structure of a silver atomic cluster (Ag@)/silver chloride photocatalyst using in situ precipitation 3D printing technique). The as-prepared photocatalyst structure exhibited high porosity and was tested for photocatalytic dye degradation and sterilization of Escherichia coli under visible and ultraviolet light irradiation. The results showed that the photocatalyst structure demonstrated strong degradation efficiency towards aqueous solutions of Orange II azo dye and methylene blue dye, and the kinetic properties followed a pseudo-first-order kinetics. The photocatalyst structure also exhibited efficient sterilization of E. coli, and the kinetics followed a pseudo-first-order and hyperbolic kinetics. Furthermore, after five cycles of dye degradation, the photocatalyst structure maintained high degradation rates of approximately 89.8% and 88.2% for Orange II azo and methylene blue dyes, respectively, indicating excellent durability and reliability of the prepared photocatalyst structure.
