Piezoelectric materials: Advanced applications in electro-chemical processes

This review article provides a detailed overview of the advanced applications of piezoelectric material in electrochemical processes. Energy harvesting, a potential topic, aims to transform ambient energy sources, including heat, light, and mechanical motion, into useful energy that would otherwise be wasted. This review focuses on an innovative and developing field that intends to connect-directly energy-harvesting devices and materials to the electrochemical systems. To regulate electrochemical processes in presence of piezoelectric materials, electrochemical reactions are dominantly influenced by produced electric charge under mechanical stress. In detail, the applications of piezoelectric material electrochemistry involved for dye degradation, hydrogen production, self-charging power cells, nanogenerator and water splitting is discussed under the umbrella of piezocatalysis. A very focused data is presented for piezo electrochemical hybrid systems from the future perspective and the potential applications for current enhancement induced by internal piezoelectric effect of the systems are also highlighted.
