The purpose of this study is to improve the efficiency of decontamination using BaSO as a piezocatalyst. Three techniques are employed in this study to enhance the piezocatalytic activity of BaSO. The first method involves coupling BaSO with BaTiO. The acid red 151 and acid blue 113 decontamination rates improved from 56.7% and 60.9% to 61.3% and 64.4%, respectively, as a result of this strategy. Additionally, the composite of BaSO and BaTiO was doped with copper, iron, sulfur, and nitrogen. By doping BaTiO, acid red 151 and acid blue 113 achieved 86.7% and 89.2% efficiency, respectively. Finally, the nanostructures were modified with sucrose. These strategies improved degradation efficiency for acid red 151 and acid blue 113 to 92.9% and 93.3%, respectively. The reusability results showed that the piezo-catalytic activity of the m-S-BaSO-BaTiO catalyst did not show a significant loss after five recycles for the degradation of AB113.
本研究旨在提高 BaSO 作为压电器催化剂的去污效率。本研究采用了三种技术来提高 BaSO 的压催化活性。第一种方法是将 BaSO 与 BaTiO 结合。酸红 151 和酸蓝 113 的去除率分别从 56.7%和 60.9%提高到 61.3%和 64.4%。此外，BaSO 和 BaTiO 的复合材料还掺杂了铜、铁、硫和氮。通过掺杂 BaTiO，酸红 151 和酸蓝 113 的效率分别达到了 86.7%和 89.2%。最后，采用蔗糖对纳米结构进行修饰。这些策略将酸红 151 和酸蓝 113 的降解效率分别提高到了 92.9%和 93.3%。可重复使用性结果表明，在五次 AB113 降解循环后，m-S-BaSO-BaTiO 催化剂的压电催化活性没有明显损失。
