Abstract
The six-layered Aurivillius compound, Bi7Fe3Ti3O21 (BFT) ceramic, is renowned for its interesting dielectric properties. With a visible range energy band gap (~ 2.20 eV) and piezoelectric characteristics, it emerges as a promising candidate for both photocatalytic and piezocatalytic applications in the degradation of organic pollutants. The current investigation explores the potential of utilizing BFT ceramic as a catalyst, investigating its performance in photocatalytic and piezocatalytic activities for the degradation of a representative pollutant named Methylene Blue (MB) dye. This research also covers tribocatalytic assessment of BFT, focusing on its performance in a catalytic process that utilizes low-frequency mechanical energy. The findings reveal that the piezocatalytic efficiency (~ 82% in 2 h) of BFT ceramic surpasses that of other catalysis processes examined in this study.
