Abstract
Ti-BiOCl nanowires with high deformation ability and high photoelectric response ability were prepared by a one-step hydrothermal method. Ti-BiOCl nanowires exhibited excellent piezoelectric photocatalytic degradation activity for refractory TC. The degradation efficiency of TC (C0 = 15 mg/L) by Ti-BiOCl nanowires reached 93.97% in 10 min under the cooperative action of light and ultrasonic. The possible piezoelectric photocatalytic degradation process of TC was similar to the general photocatalytic process. However, the reaction rate was much faster, with a primary reaction rate constant of 0.318 min−1 at room temperature.
