Piezoelectric-Induced Internal Electric Field in Bi₂WO₆ Nanoplates for Boosting the Photocatalytic Degradation of Organic Pollutants

Photocatalytic Degradation of Organic Pollutants in Water

A photocatalyst is defined as a substance which is activated by adsorbing a photon and is capable of accelerating a reaction without being consumed [1]. These substances are invaria‐ bly semiconductors. Semiconducting oxide photocatalysts have been increasingly focused in recent years due to their potential applications in solar energy conversion and environmen‐ tal purification. Semiconductor ...

Photocatalytic Degradation of Organic Pollutants: Mechanisms and Kinetics

A wide variety of organic pollutants are introduced into the water system from various sources such as industrial effluents, agricultural runoff and chemical spills (Muszkat et al., 1994; Cohen et al., 1986). Their toxicity, stability to natural decomposition and persistence in the environment has been the cause of much concern to the societies and regulation authorities around the world (Dowd ...

Study nanostructures of semiconductor zinc oxide (ZnO) as a photocatalyst for the degradation of organic pollutants

In the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (ZnO) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. Previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...
