SrO-Bi2O3-B2O3 (SBBO) transparent glasses were fabricated via the conventional melt quenching technique. X-ray diffraction (XRD) was carried out to confirm the glassy nature. Differential scanning calorimetry (DSC) was utilized to gain knowledge about the crystallization temperature, and following that glass samples were heat-treated to achieve crystallinity. The obtained values of the glass transition temperature (T g), the onset of crystallization temperature (T cr), and the peak crystallization (T p) temperature are 408, 438, and 440 °C, respectively. The glasses were heated at 440 °C for 30 min, 1 h, and 2 h to form glass-ceramics. The SrBi2B2O7 phase was formed during 1 h of heat treatment of the glasses. Studies of active vibration modes were done by Raman spectroscopy for SBBO glass and glass-ceramic samples. Piezocatalysis experiments were carried out for the removal of organic pollutants with Methylene Blue (MB) dye as a model dye, and the obtained maximum dye degradation was 51% with a kinetic rate of 0.002 min–1 under 240 min of ultrasonication. Experiments were repeated for 5 cycles to confirm the repeatability, and different dyes were used for degradation to confirm the reliability of the prepared glass-ceramic sample. Furthermore, Vigna radiata seeds were used to study the byproduct of dye that had been degraded for the assessment of phytotoxicity.

“…[ 43 ] According to Tudela's work, the size and geometry would also impact the polarization, and thereby the resonance frequency of piezoelectric materials. [ 44 ] However, a simple translation of theory built for bulk material is not necessarily true for nanoparticles. More experimental investigation and new theoretical modes should be considered in future researches.…”

Comprehensive Summary Recently, piezocatalysis has attracted considerable attention as a new type of renewable mechanical energy conversion technology, which relies on the strain induced polarization of the piezoelectric material. This new technology has been extensively applied in the applications of water splitting, water remediation, gas purification and tumor therapy. Despite the rapid development in the piezocatalysis, the utilization of piezoelectric materials for synthetic purpose is still under exploration. Piezoelectric means to promote organic reactions expand the scope of piezoelectrically mediated reactions and show successes in both organic and polymer synthesis. Herein, we provide a comprehensive review on recent progress of piezoelectrically mediated reactions, catalytic mechanisms and applications in the last few years. The limitations and future directions of this area are also discussed. We believe this review will provide new insights into the underlying mechanism of piezoelectric mediated electron transfer process and guide the design of new chemistry.
