“…The literature indicates that the synthesized NiO x / In 0.9 Ni 0.1 TaO 4 photocatalyst display water splitting into H 2 and O 2 in a stoichiometric amount under visible-light irradiation. Since then, many novel photocatalysts have been found with activity under visible-light irradiation, such as Bi 2 RNbO 7 (R = Y, Rare Earth) [8], BiVO 4 [9,10], Bi 2 WO 6 [11], FeWO 4 [12], FeNbO 4 [13], and so on. The band gap of the above materials is appropriate for absorption of visible light and therefore they have activity under visible-light irradiation.…”

Gd 2 O 3 /Ag 3 VO 4 photocatalysts are synthesized through the impregnation method and characterized by powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and UV-vis diffuse reflectance spectra (DRS). It is shown that Gd 3? is dispersed on the surface of Ag 3 VO 4 in the form of Gd 2 O 3 . The DRS analysis indicates that the ability of visible-light absorption of Gd 2 O 3 /Ag 3 VO 4 catalysts is enhanced greatly. The photocatalytic activities of the samples are evaluated by degradation of Rhodamine B dye under UV and visible-light irradiation, respectively. The experimental results show that the role of Gd 2 O 3 content has a significant impact on the photocatalytic activities of the samples. The mechanism of enhanced photocatalytic activity after the Gd introduction is discussed.

“…These noble metal nanoparticles (NPs) had play on serving as electron sinks and to facilitate interfacial electron transfer, but large NPs may also consume holes, thus serving as recombination centers. In fact some kinds of metal-loaded visible-light-driven photocatalysis were synthesized, as Mo-BiVO 4 [17], AgBiVO 4 [17], Pd/BiVO 4 [18], Cu-BiVO 4 [19], Ni-BiVO 4 [20], Au/BiVO 4 [21] and the metals existed as oxides on the surface of the particles. These powders had better degradation rate than that of pure BiVO 4 , probably due not only a decrease of energy band gap and isoelectric point, but also the augmentation of surface absorption.…”

“…We can load BiVO 4 with some metals to improve its absorption and obtain photocatalyst with enhanced catalytic activity. Up to now, there are many reports on development of doping BiVO 4 with Pd [7], Cu [10], Ag [11], Pt [12] mainly by means of hydrothermal method or precipitation procedure, however there is nothing about BiVO 4 doped by Zn on photocatalyst except on environmentally friendly yellow pigments [13]. And precursor Zn(NO 3 ) 2 was used for spot array preparation in aqueous solution, it show that doping of Zn into BiVO 4 increases the photocurrent for sulfite oxidation on BiVO 4 for scanning electrochemical microscopy (SECM) [14].…”

Abstract-UsingBi(NO 3 ) 3 ·5H 2 O, NH 4 VO 3 and Zn(NO 3 ) 2 ·6H 2 O as raw material, Zn-doped BiVO 4 photocatalysts were successfully prepared by a lowtemperature grinding synthesis. And the samples were characterized by X-ray diffraction (XRD), Infrared spectroscopy (FT-IR) and UV-Vis diffuse reflectance spectroscopy (DRS). The Methyl Orange (MO) was simulated as the sewage under the visible light to study the influence of the illumination time and the amount of photocatalyst. The visible-light absorption scope of BiVO 4 was broaden by doping Zn 2+ , the UV-Visible absorption edge was slightly red shifted and the band gap was narrowed comparing with the pure BiVO 4 . It was found that the catalytic effect of the Zn-doped catalysts was enhanced under the visible-light irradiation. The cause of enhanced catalytic effect has also been analyzed and discussed in the article.
