Sonochemical synthesis of photocatalysts and their applications

Sonochemical synthesis has flourished significantly in the last few decades for the preparation of photocatalysts. A large number of photocatalysts have been prepared through sonochemical techniques. This review highlights the scope of sonochemistry in the preparation of photocatalysts, and their applications in energy production and environmental remediation. Beside, the sonochemical degradation of pollutants is discussed in detail. The progress made in sonochemical synthesis and the future perspective for this technique are summarized here. This review may create more enthusiasm among researchers to pay extra attention to the sonochemical synthesis of materials and add their useful contribution to the investigation of new materials for photocatalytic and other applications. This will propel this technique toward commercial sonosynthesis of nanomaterials.
