Synthesis of nano-anatase by sonochemistry assisted alkalihydrolysis process

Abstract

Synthesis ofanatase spherical particles bv ultraound assisted alkali hydrolvsis ofanatase was investigated. The dispersion of anatase in NaOH solution was treated by ultrasound with 2.5 MHz. The obtained anatase was characterized by XRD, SEM, and SEM. Sonochemistrv treatment enhances chemical reactivity of anatase solid surface witti NaOH. The sonochemistry treatment with acoustic cavitation pulverized the raw anatase into nanometer size. The present process with low cost starting materials and simple operation makes possible to prepare relatively large quantities and high yield of nano structured titanate.
