The Effect of High-frequency Ultrasound on the Photocatalytic Decomposition of Organic Compounds in Water

Access to clean water is necessary for the well-being and economic development of society. Thus, water contamination from human activity such as industry is a serious threat. Recently, the method in which organic contaminants in water are decomposed by photocatalysis has been proposed. However, the...
