Bismuth oxyiodide and silver phosphate nanoparticles (NPs) were synthesized in-situ and mechanically mixed to obtain BiOI-Ag₃PO₄ nano-composite (NC). A body-centered cubic structure of Ag₃PO₄ and the tetragonal BiOI were detected in the XRD pattern of NC with a crystallite size of 37 nm (obtained by Scherrer equation). The absorption edge wavelengths (λ_AE) of 571, 665, and 745 nm were respectively obtained for the Ag₃PO₄, BiOI, and the NC samples, corresponding to the bandgap energies of 2.17, 1.86 and 1.66 eV, respectively. BiOI, Ag₃PO₄, and the NC catalysts degraded about 37, 48, and 61% of diclofenac (DCF) molecules, respectively. The composites with the Ag₃PO₄: BiOI mole ratios of 1:4 and 2:1 showed the highest photocatalytic activities, and the apparent first-order rate constants of 0.0187 and 0.0224 min⁻¹, respectively. The photodegradation of DCF molecules showed an apparent rate constant of 0.024 min⁻¹ corresponds to t_1/2 value of 28.9 min. The DCF mineralization also showed an apparent rate constant of 0.029 min⁻¹ which corresponds to t_1/2 value of 23.9 min obtained by applying the Hinshelwood model on the results obtained by COD results of the photodegraded DCF solutions.

原位合成氧化碘化铋和磷酸银纳米颗粒（NPs）并机械混合，得到BiOI-Ag ₃ PO ₄纳米复合材料（NC）。在NC的X射线衍射图中检测到Ag ₃ PO ₄和四方BiOI的体心立方结构，其微晶尺寸为37 nm（通过Scherrer方程获得）。吸收边波长（λ _AE分别为银获得的571，665，和745纳米）₃ PO ₄，BiOI和NC样品中，对应于2.17，1.86和1.66电子伏特的带隙能量，分别。BiOI，Ag ₃ PO ₄，而NC催化剂分别降解了约37％，48％和61％的双氯芬酸（DCF）分子。Ag ₃ PO ₄：BiOI摩尔比为1：4和2：1的复合材料表现出最高的光催化活性，表观一级速率常数分别为0.0187和0.0224 min ^-1。DCF分子的光降解显示出表观速率常数为0.024min ^-1，对应于t _1/2值为28.9min。DCF矿化还显示出表观速率常数为0.029min ^-1，其对应于通过对光降解DCF溶液的COD结果获得的结果应用Hinshelwood模型获得的t _1/2值为23.9min。
