Abstract: Several TiO 2 -based photocatalytic systems that have considerable visible light response have been developed, such as the photodegradation of organic pollutants on sensitized TiO 2 by visible light, construction of visible-light-active novel TiO 2 photocatalysts by matrix or surface modification. In this paper, we review briefly our recent progress in the TiO 2 photocatalytic degradation of organic pollutants by visible light, some related work by other groups is also involved.

“…Degradation of MO was visualized by decrease in peak intensity within 6 h of incubation time. There is no considerable shift in peak position for MO solution without exposure to biosynthesized AgNPs of sample S, R and L. Visible light was found to be faster in decolorizing dyes in the presence of metal catalyst [28,29]. The adsorption of AgNPs on to the MO solution was initially low and further increased with constant increase in time.…”

“…In 1972, Fujishima and Honda (Fujishima & Honda, 1972) discovered the photocatalytic properties of nanocrystalline TiO 2 and predicted its possible application in chemical decontamination (Linsebigler et al, 1995;Wold, 1993). The TiO 2 /UV system was described in several studies (Mills & Hunte, 1997;Peral et al, 1997;Rauf & Ashraf, 2009;Tschirch et al, 2008;Zhao et al, 2005), mainly with regard to a higher efficiency of degradation of chemical pollutants in water and air. Total mineralization of pollutants was observed, producing only CO 2 , H 2 O and inorganic ions (Zhao et al, 2005).…”

“…Therefore, design and fabrication of efficient semiconductor photocatalyst has attracted great attention in the field of photo-catalytic degradation of organic pollutants. [5][6][7] The band gap width, microstructure and composited model of semiconductor take an important role in optimize the photocatalytic activities of photocatalyst, So many researchers have focused on the design and fabrication of novel semiconductor photocatalyst. MgFe 2 O 4 is a kind of spinel semiconductor, which has a cubic structure of normal spinel-type and soft magnetic property.…”
