Active photocatalysts with an efficiency of 99% were prepared for the degradation of the industrial dye, methylene blue (MB), under visible light irradiation. These photocatalysts comprised Co/Ni-metal-organic frameworks (MOFs), to which bismuth oxyiodide (BiOI) was added as a filler to prepare Co/Ni-MOF@BiOI composites. The composites exhibited remarkable photocatalytic degradation of MB in aqueous solutions. The effects of various parameters, including the pH, reaction time, catalyst dose, and MB concentration, on the photocatalytic activity of the prepared catalysts were also evaluated. We believe that these composites are promising photocatalysts for the removal of MB from aqueous solutions under visible light.
制备了可见光照射下对工业染料亚甲基蓝（MB）降解效率达99%的活性光催化剂。这些光催化剂由钴/镍金属有机框架（MOF）组成，向其中添加了碘氧化铋（BiOI）作为填料以制备钴/镍-MOF@BiOI复合材料。该复合材料在水溶液中对MB表现出显著的光催化降解性能。还评估了包括pH值、反应时间、催化剂用量和MB浓度等各种参数对所制备催化剂光催化活性的影响。我们认为这些复合材料是在可见光下从水溶液中去除MB的有前景的光催化剂。
