Ultrasonic synthesis of nanomaterials for photocatalytic removal of pollutants from wastewater #19

Abstract

Photocatalysis is an efficient and sustainable way to the removal of pollutants from wastewater. Ultrasound technology provides the opportunities for the quick and facile synthesis of photocatalytic nanomaterials. This paper is devoted to a comprehensive perspective of ultrasonic synthesis of nanomaterials for photocatalytic removal of pollutants from wastewater. Ultrasonic synthesis of the three categories of photocatalytic nanomaterials including semiconductors, doped semiconductors, and compound semiconductors is involved. Especially, the very recent developments in the ultrasonic synthesis of semiconductor materials such as heterostructures, hybrid semiconductors, noble metal-deposited semiconductors, sensitized semiconductors, and supported semiconductors are summarized. On this basis, the outlook on ultrasonic synthesis of photocatalytic nanomaterials is provided.
