Abstract
Mechanical energy is a natural energy that can be considered as a form of rich, clean, and renewable energy and it can be harvested by using piezoelectric materials. Water pollution is one of the series of threats faced by our planet and jeopardizes the ecosystem. Piezocatalysis could be a promising solution for this issue. This research focused on the sonochemical synthesis of PbTiO3 (PTO) piezocatalyst and studied the effect of synthesis parameters, operation conditions during the piezocatalysis process, and the effect of DNA as a modifier on piezocatalytic activity of PTO. Results showed that the synthesis parameters show a significant effect on the piezocatalytic activity of PTO. The origin of this effect came from the morphology, purity, and orientation of final products. Results displayed that the degradation reaction was completed during the first hour. 97.1 % of Acid Red 141 (AR141) was degraded by controlling both synthesis and operation conditions. In this research, the ultrasonic probe with a power of 100–600 W and a frequency of 18 kHz was used.
