Photocatalytic properties and degradation mechanisms of organics play an important role in removing the poisonous organic compounds from wastewater. In order to reveal the degradation mechanisms and photocatalytic properties of all kinds of organic compounds, some corresponding articles should be reviewed, and different preparation methods for some new photocatalysts should be summarized, at the same time, t Read More

Titanium dioxide (TiO2) is ideally most promising photocatalyst for degradation of organic compounds under environmentally benign conditions. For further exploitation of its catalytic properties, some strategies to improve adsorption of organic substrates by hybridization with various support materials have become important. This article reviews recent developments in designing TiO2 photocatalyst with the objective of fabric Read More

The codoping of TiO2 provides a promising approach to extend the photo-response of TiO2 to the more abundant visible region and emerges as a very active research field in the photocatalytic degradation of organic pollutants very recently. The present review first gives an overview on the general performance of the co-doped TiO2 visible-light photocatalysts and then the current progresses in the synthetic methods and str Read More

In this review, three degradation mechanisms, pathways and intermediate products of various organic compounds for photocatalytic degradation by using different photocatalysts are discussed in detail. Three degradation mechanisms are as following: (1) Holes in valence bond and resulting OH˙ radicals generated from holes oxidize the organics, (2) resulting OH˙ radicals and the O2 ˙¯ generated from conduction band electr Read More

Photocatalytic degradation of organic chemicals enjoys fast development now and great achievements have been made over the past few decades. Photocatalysts, as the core of photocatalytic system, have been tremendously studied. Various methods to prepare photocatalysts have been developed for changing the photoelectrochemical characteristics and improving the photocatalytic activity. In this way, a great nu Read More

Titanium dioxide photocatalysts having anatase and rutile phases are a promising substrate for photodegradation of pollutants in water and air. However, their photocatalytic activities show only under ultraviolet (UV) light. In order to utilize a wide range of incident light such as solar light, development of the photocatalysts whose activities show under visible light is one of the most important strategies. We and other resear Read More

This review describes recent development of photocatalysts and their performance in degrading organics.
