“…Bismuth sodium titanate (Na 0.5 Bi 0.5 TiO 3 ) is a type of representative ferroelectric and belongs to the ABO 3 perovskite family with equational occupation of Na + and Bi 3+ in A-site, which owns high conductivity and Curie temperature, moderate piezoelectric coefficient and band gap, and has shown potential applications in photocatalysis, piezocatalysis, and piezo-photocatalysis fields. − However, its catalytic activity is not high enough because of its relative wide band gap and relatively low piezoelectric coefficient . For overcoming its deficiencies, some techniques have been developed by researchers, such as ions doping, ,− formation of heterojunction with other materials, ,, and plasmonic effect. , …”

A series of Na0.5Bi0.5TiO3-based catalysts were synthesized by using the solvothermal route. The successful synthesis of catalysts was confirmed by various measurements. The influence of Y3+ doping on the band gap was revealed by the UV–visible absorbance spectra. Their photocatalytic, piezocatalytic, and piezo-photocatalytic activities were investigated by degrading methylene blue. The results show that the Y3+ doping can enhance the catalytic activity of Na0.5Bi0.5TiO3 due to the more efficient harvesting of light, and the catalytic activity can be further enhanced by the support of polyacrylonitrile nanofibers on account of the existence of more active sites. The reaction constants of Na0.5Bi0.485Y0.015TiO3 and Na0.5Bi0.485Y0.015TiO3@PAN in photocatalysis processes are 0.0075 and 0.0112 min–1, which is 1.23 and 1.84 times as many as that of Na0.5Bi0.5TiO3. In addition, the catalysts show higher catalytic activities when the catalysis is carried out at the operating condition including both simulated sunlight irradiation and ultrasonic vibration. The reaction constant of Na0.5Bi0.485Y0.015TiO3@PAN in piezo-photocatalysis is 0.0381 min–1, which is 3.09 and 6.77 times of photocatalysis and piezocatalysis. The enhanced activity results from suppression of charge carrier recombination. The radicals of •O2 – and h+ play actual roles in the catalytic processes.

In this comprehensive review article, we delve into the critical intersection of environmental science and materials science. The introduction sets the stage by emphasizing the global water shortage crisis and the dire consequences of untreated effluents on ecosystems and human health. As we progress into the second section, we embark on an intricate exploration of piezoelectric and photocatalytic principles, illuminating their significance in wastewater treatment and sustainable energy production. The heart of our review is dedicated to a detailed analysis of the detrimental impacts of effluents on human health, underscoring the urgency of effective treatment methods. We dissected three key materials in the realm of piezo-photocatalysis: ZnO-based materials, BaTiO3-based materials, and bismuth-doped materials. Each material is scrutinized for its unique properties and applications in the removal of pollutants from wastewater, offering a comprehensive understanding of their potential to address this critical issue. Furthermore, our exploration extends to the realm of hydrogen production, where we discuss various types of hydrogen and the role of piezo-photocatalysis in generating clean and sustainable hydrogen. By illuminating the synergistic potential of these advanced materials and technologies, we pave the way for innovative solutions to the pressing challenges of water pollution and renewable energy production. This review article not only serves as a valuable resource for researchers and scholars in the fields of material science and environmental engineering but also underscores the pivotal role of interdisciplinary approaches in addressing complex global issues.
