Ball milling–based piezocatalysis using .5Ba(Zr_0.2Ti_0.8)O₃–.5(Ba_0.7Sr_0.3)TiO₃ ceramics

Abstract

One of the newly light on processes utilized in applications for cleaning water is piezocatalysis. Mechanical vibrations generated through ultrasonication are generally used to separate out the charges in ferroelectric ceramics. The current research presents a novel prospective methodology of ball milling, where it is used as a facile and green technique for water remediation. The movement of the planetary ball mill imparts enough force such that reactive species are produced which are responsible for organic dye degradation. One of the results in the parametric analysis showed that by using 0.30 g of the 0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Sr0.3)TiO3 (BST–BZT) powder, 62% of the methylene blue (MB) dye was degraded in 60 minutes.
