“…Semiconductor photocatalysts have attracted considerable attention in recent years due to its wide application in pollutant degradation and hydrogen production from splitting water using solar energy [1,2]. Among various semiconductor materials, TiO 2 semiconductor has been mostly investigated owing to the non-toxicity, low cost, relatively high chemical stability, and strong oxidizing power [3,4].…”

Novel CdS/BiOI heterojunction photocatalysts were successfully prepared by facile method. The as-prepared samples were characterized by transmission electron microscopy, field-emission scanning electron microscopy, Xray diffraction, the Raman spectroscopy, UV-vis diffuse reflectance spectra, the Fourier transform infrared spectra, and photoluminescence. It was found that CdS nanoparticles were uniformly distributed on the surface of BiOI microspheres. The photodegradation tests showed that the photocatalytic efficiency was increased at first and then decreased when further increasing CdS content in the nanocomposites. The highest activity was obtained by 3%-CdS/BiOI nanocomposites. The enhanced photocatalytic performances were attributed to the matched band potentials of CdS and BiOI, which resulted in the efficient separation of photogenerated electron-hole pairs. Based on the experimental results, a reasonable photocatalytic mechanism of CdS/BiOI photocatalysts was also proposed.

“…However, due to the high electron-hole recombination rate, the efficiency of In 2 O 3 is still limited. In order to improve the photocatalytic activity of In 2 O 3 , researchers have used a variety of methods, such as morphology control [6,7], metal deposition [8], and combining with semiconductors [9][10][11].…”

important practical value to prepare photocatalytic materials with high activity under visible light.Indium oxide (In 2 O 3 ), a n-type semiconductor material, has a direct band gap of 3.8 eV and an indirect band gap of 2.8 eV [2]. It is an effective sensitizer and its absorption spectrum can extend from ultraviolet region to the visible region. It has been widely used in solar cells [3], flat panel display [4], gas sensor [5]. However, due to the high electron-hole recombination rate, the efficiency of In 2 O 3 is still limited. In order to improve the photocatalytic activity of In 2 O 3 , researchers have used a variety of methods, such as morphology control [6,7], metal deposition [8], and combining with semiconductors [9][10][11].Graphitic carbon nitride (denoted as C 3 N 4 ) is a kind of medium band gap (2.7 eV) nonmetal photocatalyst [12]. It has good chemical stability and thermal stability. Furthermore, it can be used to split water into H 2 and O 2 and degrade organic pollutants under visible light irradiation [13]. But high photoproduction electron-hole recombination rate seriously affects the catalytic properties of C 3 N 4 . C 3 N 4 can be easily adhered on the surface of other compounds due to its softness. Deferent types of strategies have been used to make the catalytic properties of C 3 N 4 better, including coupling with metals [14][15][16] [29]. Compared with the original semiconductor materials, the photocatalytic performance of these composites were enhanced obviously. Through mechanism analyzing, the reason for photocatalytic performance enhancements may be the improvement of electron-hole migration and separation.Recently, some investigations about In 2 O 3 /C 3 N 4 were reported. In 2 O 3 /C 3 N 4 composites can be used for hydrogen evolution
