Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 62(5)

Published: Nov. 1, 2022

Abstract As a consequence of rapid industrialization throughout the world, various environmental pollutants have begun to accumulate in water, air, and soil. This endangers ecological environment earth, remediation has become an immediate priority. Among techniques, piezocatalytic which uniquely take advantage piezoelectric effect, attracted much attention. Piezoelectric effects allow pollutant degradation directly, while also enhancing photocatalysis by reducing recombination photogenerated carriers. In this Review, we provide comprehensive summary recent developments techniques for remediation. The origin effect as well classification materials their application are systematically summarized. We analyze potential underlying mechanisms. Finally, urgent problems future development discussed.

Abstract Piezoelectric mesocrystals as defective materials have been demonstrated to possess adsorptive and catalytic properties in redox reactions. However, there is still a lack of research on the quantitative relationship between defect concentration piezocatalytic performance piezoelectric mesocrystals. Herein, twin‐hierarchical structure ZnO are taken with different oxygen‐vacancies (OVs) concentrations quantitatively investigate effect content peroxymonosulfate (PMS) piezo‐activation water purification. The mesocrystal moderate OVs exhibits rapid antibiotic ornidazole (ORZ) pollutants degradation rate (0.034 min −1 ) achieves high PMS utilization efficiency (0.162) that exceeds most state‐of‐the‐art processes, while excessive suppressed performance.
