Abstract
This study investigates the catalytic performance and synergistic effect of Sr2Bi4Ti5O18 (SBT) powder in degrading Rhodamine B (RhB) dye through photocatalysis, tribocatalysis, and photo-tribocatalysis. The synthesized (solid-state reaction route) SBT powder was characterized using Raman spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The catalytic performance was evaluated at different stirring rates, with tribocatalysis at 600 rpm achieving approximately 92 % dye degradation within 12 h. In 90 min, photocatalysis and tribocatalysis individually degraded about 24 % and 30 % of the dye, respectively. However, the combined photo-tribocatalysis showed enhanced performance, reaching 56 % degradation within the same duration, indicating a synergistic improvement of around 19 %. Furthermore, ball milling the SBT powder for 12 h significantly enhanced its catalytic activity, achieving approximately 97 % degradation in 90 min.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
