Abstract
In this paper, we generate piezoelectricity in one-directionally aligned bi-axially grown ZnO nanorods. The applied force is horizontal to the polarization direction. The piezophototronic induced voltage generation from a bending radius is experimentally measured for ZnO NRs. The combination of photo catalytic effect and piezoelectrochemical phenomenon of ZnO NRs has been used for the degradation of an organic pollutant in the aqueous medium. The mechanical stress creates a polar charge field on the surface of ZnO NRs, which acts as a driving force to enhance the charge separation of photo generated electron and hole pairs. Subsequently, the charge separation increases the photo catalytic activity of ZnO NRs. Further coumarin (COU), used as a fluorescent probe for the purpose of detection and measurement of OH. Radical is generated during photo catalysis process. The synergistic effect of strain-induced chemical reactions and UV photo catalytic activity can deliver a lucrative approach for degradation of organic pollutants. In addition, this work exhibits an exciting new model of a piezophototronic device.
