Piezo-Catalytic Techniques in Environmental Remediation.

Abstract

Due to the rapid industrialization across the world, various environmental pollutants have begun to accumulate in water, air and soil. This endangers the ecological environment of the earth, and environmental remediation has become an immediate concern. Among various environmental remediation techniques, piezo-catalytic techniques uniquely take advantage of piezoelectric effect, has attracted much attention. Piezoelectric effects allow for pollutant degradation directly, while also enhancing photocatalysis by reducing photogenerated carriers recombination. In this review, we provide a comprehensive summary of recent developments of piezo-catalytic techniques for environmental remediation. The foundation of piezoelectric effect, classification of piezoelectric materials and its application in environmental remediation are systematically summarized. We also analyze the potential underlying mechanisms. Finally, the urgent problems and prospects of piezo-catalytic techniques are discussed.
