Research progress in enhancing the efficiency of piezoelectric catalytic degradation of organic pollutants from water
Water pollution and energy shortage are global problems that are gaining significant attention.Piezoelectric catalysis can convert external mechanical energy into chemical energy.As a green,effective,and energy-saving technology,piezo-catalysis has the potential to solve the above issues.However,the oxidation capacity of a simple piezoelectric system is limited,and the target pollutants are concentrated in degradable organic pollutants with low-concentration in water.To solve the above problems,researchers have employed various methods to enhance the oxidation capacity of the piezoelectric system.Three types of piezoelectric catalytic strengthening methods commonly used were summarized,including regulation of piezoelectric materials,coupling of chemical reagents,and optimization of piezoelectric driving approaches.Besides,the significance of energy and environment as well as the prospects of piezo-catalysis were discussed.
