摘要：

0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Sr0.3)TiO3 (BST-BZT) ceramic composition is known for exihi-biting electrical properties. The present study brings out the prospective approach of uti-lizing well known BST-BZT ceramic composition for water cleaning application via piezocatalysis, photocatalysis and piezo-photocatalysis process. For this, BST-BZT ceramic composition was synthesized through solid state route reaction method and was charac-terized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectros-copy and X-ray photoelectron spectroscopy (XPS). Methylene Blue (MB) a cationic dye was used as a representative organic pollutant, where the maximum degradation was observed in piezo-photocatalysis process (-92%) followed by photocatalysis process (-82%) and piezocatalysis process (-65%) in 240 min. Furthermore, the degradation of MB dye was examined under solar light irradiation in order to assess the potential of the BST-BZT ceramic composition. A study on the BST-BZT ceramic composition's photocatalytic ac-tivity in an indoor setting was also conducted. Finally, the phytotoxicity level of "Vigna radiata" seeds was examined to determine the extent of MB dye breakdown and its sub-sequent usage. (c) 2023 The Authors. Published by Elsevier B.V.
