TiO2–Zeolite Metal Composites for Photocatalytic Degradation of Organic Pollutants in Water

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 Application of Titania Nanoparticles for Degradation of Organic Pollutants

2D Transition Metal Dichalcogenides and Graphene-Based Ternary Composites for Photocatalytic Hydrogen Evolution and Pollutants Degradation

Photocatalysis have attracted great attention due to their useful applications for sustainable hydrogen evolution and pollutants degradation. Transition metal dichalcogenides (TMDs) such as MoS₂ and WS₂ have exhibited great potential as cocatalysts to increase the photo-activity of some semiconductors. By combination with graphene (GR), enhanced cocatalysts of TMD/GR hybrids could be synthesize...

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 ...

A Photocatalytic Method for the Degradation of Pyrrolidine in Water

A method for the degradation of pyrrolidine in water is described. The method relaies on the photocatalytic degradation of pyrrolidine to CO2 and NH3 by UV irradiation and using titanium dixide semiconductor as a photocatalyst. Compared with direct photolysis, the semiconductor catalytic photolysis gave consistently higher degradation yields for pyrrolidine in water. T...
