Boost piezocatalytic activity of BaSO₄ by coupling it with BaTiO₃, Cu:BaTiO₃, Fe:BaTiO₃, S:BaTiO₃ and modify them by sucrose for water purification.

ABSTRACT: The purpose of this study is to improve the efficiency of decontamination using BaSO₄ as a piezocatalyst. Three techniques are employed in this study to enhance the piezocatalytic activity of BaSO₄. The first method involves coupling BaSO₄ with BaTiO₃. 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 BaSO₄ and BaTiO₃ was doped with copper, iron, sulfur, and nitrogen. By doping BaTiO₃, 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-BaSO₄-BaTiO₃ catalyst did not show a significant loss after five recycles for the degradation of AB113.
