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.

“…In addition, the difference of energy band structure of different crystal planes drives carriers to migrate to different facets, which facilitate the charge separation process. , Reasonable adjustment of the exposed crystal facets has been proved to be an effective strategy to improve the activity of the catalyst . Li et al synthesized BiOCl of (001) facets or (101) facets by hydrothermal method. BiOCl with more exposed (001) facets have higher piezoelectric activity because of its high piezoelectric coefficient, high charge separation efficiency, more active sites, and narrow band gap.…”

Reasonable adjustment of the exposed crystal facets has been proven to be an effective strategy to improve the activity of the catalyst. However, the crystal-facet-dependent piezoactivity is rarely investigated. In this work, BiFeO 3 with highly exposed (012) or (110) crystal facets were synthesized by adjusting the volume ratio of solvent and reaction time. Ethylene glycol was used as a structure-directing agent for the synthesis of BiFeO 3 nanosheets (BiFeO 3 −NS) with highly exposed (012) facets. BiFeO 3 −NS shows an obvious higher piezoelectric catalytic hydrogen evolution rate than that of BiFeO 3 nanoparticles (BiFeO 3 − NP) with highly exposed (110) facets. In addition, the rate constant of BiFeO 3 −NS for the piezocatalytic degradation of rhodamine B (RhB) shows a 2-fold increase than that of BiFeO 3 −NP. A variety of controlled experiments have been performed. It is revealed that these two nanomaterials exhibit comparable specific surface areas and adsorption capacity. BiFeO 3 −NS possesses narrowed bandgap as compared to that of BiFeO 3 −NP. The enhanced piezocatalytic activity of BiFeO 3 −NS can be attributed to its built-in electric field, strong carrier mobility, and effective charge separation efficiency. This study provides an alternative perspective for piezoelectric catalysis in surface engineering.

“…The surface atomic arrangement of diverse crystal facets is different, which results in the difference of the surface electronic structure. Therefore, semiconductor catalysts with different predominant facets may exhibit different band gap values and band edge positions, which affect the carrier separation efficiency and redox capacity . It can be seen that the facet engineering strategy of fully exposing the reaction facet is a promising direction for the development of novel sonocatalysts with high activity.…”

Strategically exposing active crystal facets significantly enhances the catalytic performance of the catalyst. Here, we design ultrathin BiOCl nanosheets (NSs) with nearly completely exposed active (001) crystal facets and investigate the facet-dependent catalytic activity and the underlying mechanism. With the exposure extent of active facets increased, the defect type changed from the single atom Bi vacancy defect to the adjacent Bi−O−Bi triatom association vacancy. These vacancy associates provide active sites for the adsorption and activation of the catalytic substrate on the surface, which promotes the catalytic reaction. Meanwhile, the adjustment of surface electronic structure and band structure is conducive to the decrease of the charge transfer barrier and the enhancement of carrier separation ability. In a mouse breast cancer model, ultrasound-mediated BiOCl NSs facilitated a trimodal synergistic treatment regimen comprising carbon monoxide gas therapy, sonodynamic therapy, and starvation therapy to effectively inhibit hypoxic tumor growth and proliferation.
