“…As a result of its controllable morphology, higher surface area and tunable pore diameter, mpg‐C 3 N 4 has drastically advantages to uniformly support the suitable metal oxide and it may be expected to be an effective technique for the advancement of the photocatalytic redox ability and the charge carrier generation rate . Therefore, mirroring the antecedent research , we design a new Ag 3 VO 4 /mpg‐C 3 N 4 heterojunction composite by coupling mesoporous g‐C 3 N 4 (mpg‐C 3 N 4 ) with Ag 3 VO 4 to create high‐performance photocatalytic materials for TC removal. The mpg‐C 3 N 4 hybridized with Ag 3 VO 4 would be possible preventing the aggregation of Ag 3 VO 4 particles and thus worth to try as a well reusable and high active photocatalyst.…”

Ag VO /mpg-C N (mesoporous graphitic carbon nitride) heterojunction photocatalysts were prepared by anchoring tiny Ag VO particles on the nanosheet of mpg-C N . The prepared Ag VO /mpg-C N heterojunctions were used to remove tetracycline (TC), a kind of antibiotics widely released into the aquatic environment under solar irradiation. Compared with pure mpg-C N and Ag VO , Ag VO /mpg-C N displayed much higher photocatalytic activity (83.2% removal rate within 90 min under visible-light irradiation). Importantly, no apparent deactivation was observed for Ag VO /mpg-C N -40 after five cycles, inferring a good reusability. As confirmed by photocurrent measurement and photoluminescence spectra, the excellent photocatalytic property of Ag VO /mpg-C N was credit to the electron-hole separation enhancement at the formed heterojunction of two semiconductors. In addition, a possible mechanism and intermediate products for the Ag VO /mpg-C N photocatalysts toward the photodegradation of TC in aqueous solution under artificial sunlight radiation were proposed based on the scavengers trapping test, ESR spectra and a high-performance liquid chromatography (HPLC) coupled with mass spectrometer (MS) analysis. This investigation provides a low cost, green and easily practical approach to remove the antibiotics in the aquatic environment.

“…Among these problems, the degradation of pollutants of aromatic and azo structures has attracted attention, and the use of photocatalytic technology to degrade dyes has emerged as a promising technology [1][2][3][4][5][6]. Photocatalysts, on the basis of semiconductor materials, such as TiO 2 [7][8][9], ZnO [10][11][12][13][14], CdS [15][16][17][18][19], and WO 3 [20][21][22][23][24], have caused a new upsurge in the degradation of methyl orange structure pollution due to their simplicity, high efficiency, low energy consumption, and mild reaction conditions [25]. Although these conventional semiconductor photocatalysts substantially affect the degradation of methyl orange, they also have limitations [17,20,26,27].…”

Cu3N/MoS2 composite films were prepared by magnetron sputtering under different preparation parameter, and their photocatalytic properties were investigated. Results showed that the composite films surface was uniform and had no evident cracks. When the sputtering power of MoS2 increased from 2 W to 8 W, the photocatalytic performance of the composite films showed a trend of increasing first and then decreasing. Among these films, the composite films with MoS2 sputtering power of 4 W showed the best photocatalytic degradation performance. The photocatalytic degradation rate of methyl orange at 30 min was 98.3%, because the MoS2 crystal in the films preferentially grew over the Cu3N crystal, thereby affecting the growth of the Cu3N crystal. The crystallinity of the copper nitride also increased. During photocatalytic degradation, the proper amount of MoS2 reduced the band gap of Cu3N, and the photogenerated electron hole pairs were easily separated. Thus, the films produces additional photogenerated electrons and promotes the degradation reaction of the composite films on methyl orange solution.

Residual pollutants in the water treatment process restrict the advanced treatment and purification of wastewater, because most of them have stable structures, and some are not easily to be enriched. Photocatalytic oxidation technology can directly use solar energy to drive a series of chemical reactions, which has advantages such as low energy consumption, mild reaction conditions and rarely secondary pollution. It is an effective way to solve the organic pollution problem in wastewater treatment. The key to this process is to find and design efficient photocatalysts. The current photocatalytic materials mainly include inorganic semiconductors and metal organic frameworks (MOFs). They have been studied for pollutants degradation, hydrogen evolution, CO2 reduction, and organic transformation. But, most of these catalysts have not been used in real application. In this paper, recent research advances in MOFs photocatalysts and the key factors affecting their photocatalytic efficiency were critically reviewed. It is believed that the pursuit of more efficient photocatalyst needs to be considered from the adsorption‐photocatalytic mechanism, redox‐free radical mechanism, valence‐level regulation mechanism and energy transfer mechanism of photocatalysis. It is very necessary to research and develop nanoscale and quantum level mixed valence MOFs photocatalysts, which are constructed by strong electron‐donating groups.
