Purification of wastewater by the piezo-catalyst effect of PbTiO nanostructures under ultrasonic vibration.

In this work, the piezoelectric catalytic property of PbTiO perovskite synthesized by a hydrothermal method has been investigated. The samples synthesized using no surfactant, lemon, orange, and watermelon as the surfactant. As-prepared PbTiO nanostructures as mechanical harvesting material were used to purify water containing organic contaminants.
