Hybrid H₃PMo₁₂O₄₀/polymer composites were proposed here for the simple photocatalytic decomposition of erythrosine B and rose Bengal because of their unwanted effect on the environmental microorganism. Interestingly, the composite exhibited efficient photocatalytic activity for the decomposition of dyes under both mild near UV irradiation and solar irradiation. High final conversions were obtained for both of dyes reaching 81% and 86% for the erythrosine B and rose Bengal respectively after 120 min of LED@375 nm illumination and 90% for both dyes after only 30 min of solar exposure. The photocatalytic stability was also demonstrated. The photoluminescence technique was used to prove hydroxyl radicals implication into the photo-decomposition reaction using H₃PMo₁₂O₄₀/polymer. The efficiency of the proposed treatment was confirmed by the evaluation of the ecotoxicity effect of by-products of each dye on two bacterial strains.

杂化 H ₃ PMo ₁₂ O ₄₀ /聚合物复合材料被提出用于赤藓红 B 和玫瑰红的简单光催化分解，因为它们对环境微生物有不利影响。有趣的是，该复合材料在温和的近紫外辐射和太阳辐射下均表现出有效的光催化分解染料的活性。LED@375 nm 照射 120 分钟后，赤藓红 B 和玫瑰红的两种染料的最终转化率分别达到 81% 和 86%，而两种染料在阳光照射仅 30 分钟后达到 90%。还证明了光催化稳定性。光致发光技术被用来证明羟基自由基对使用 H 的光分解反应的影响₃ PMo ₁₂ O ₄₀ /聚合物。通过评估每种染料的副产物对两种细菌菌株的生态毒性影响，证实了所提出的处理的效率。
