Abstract
Ag3PO4/Ag4P2O7 photocatalysts were successfully synthesized by microwave-hydrothermal method. Tuning the properties of photocatalysts was achieved using different amount of acetic acid (CH3COOH) and sodium hydroxide (NaOH) to adjust pH value of precursor solution (pH = 4, 7, 10 and 12). The crystal structure, morphology and optical property of samples were characterized and explained. The photocatalytic activity of sample was determined by degradation of rhodamine B (RhB) and methyl orange (MO) under a wavelength range of 350-700 nm irradiation. The results demonstrated that the change in shape of particles was not observed whereas the average particle size was decreased with increasing pH value because of the high hydroxide ions (OH-). The sample synthesized in the solution with the pH of 10 exhibited excellent photocatalytic performance and stability because of the highest surface area and the present of Ag4P2O7 on the surface of particles. The highest photodegradation efficiency was 99.34 and 96.12% by degrading RhB and MO, respectively. The enhancement of photocatalytic performance of Ag3PO4/Ag4P2O7 was discussed. The active species trapping experiments showed that the h+ was the main active species to decompose the dye molecules.

Abstract
Photocatalytic degradation, as a very significant advanced oxidation technology in the field of environmental purification, has attracted extensive attention in recent years. The design and synthesis of catalysts with high-intensity photocatalytic properties have been the focus of many researchers in recent years. In this contribution, two new supramolecular materials {[(L1)·(Ag4I7)]CH3CN} (1), {[(L2)·(Ag4I7)]CH3CN} (2) were synthesized by solution volatilization reaction of two cationic templates 1,3,5-Tris(4-aminopyridinylmethyl)-2,4,6-Trimethylphenyl bromide (L1) and 1,3,5-Tris(4-methyl pyridinyl methyl)-2,4,6-trimethylphenyl bromide (L2) with metal salt AgI at room temperature, respectively. The degradation effect of 1 and 2 as catalyst on tetracycline (TC) under visible light irradiation was studied. The results showed that the degradation of TC by 1 was better than that by 2 and both of them had good stability and cyclability. The effects of pH value, catalyst dosage, and anion in water on the photocatalytic performance were also investigated. The adsorption kinetics fit the quasi-first-order model best. After 180 min of irradiation with 1, the degradation rate of TC can reach 97.91%. In addition, the trapping experiments showed that ·OH was the main active substance in the photocatalytic degradation of TC compared with ·O2− and h+. Because of its simple synthesis and high removal efficiency, catalyst 1 has potential value for the treatment of wastewater containing organic matter.

Abstract
Semiconductor photocatalysis technology has shown great potential in the field of organic pollutant removal, as it can use clean and pollution-free solar energy as driving force. The discovery of silver phosphate (Ag3PO4) is a major breakthrough in the field of visible light responsive semiconductor photocatalysis due to its robust capacity to absorb visible light < 520 nm. Furthermore, the holes produced in Ag3PO4 under light excitation possess a strong oxidation ability. However, the strong oxidation activity of Ag3PO4 is only achieved in the presence of electron sacrifice agents. Otherwise, photocorrosion would greatly reduce the reuse efficiency of Ag3PO4. This review thus focuses on the structural characteristics and preparation methods of Ag3PO4. Particularly, the recent advances in noble metal deposition, ion doping, and semiconductor coupling, as well as methods of magnetic composite modification for the improvement of catalytic activity and recycling efficiency of Ag3PO4-based catalysts, were also discussed, and all of these measures could enhance the catalytic performance of Ag3PO4 toward organic pollutants degradation. Additionally, some potential modification methods for Ag3PO4 were also proposed. This review thus provides insights into the advantages and disadvantages of the application of Ag3PO4 in the field of photocatalysis, clarifies the photocorrosion essence of Ag3PO4, and reveals the means to improve photocatalytic activity and stability of Ag3PO4. Furthermore, it provides a theoretical and methodological basis for studying Ag3PO4-based photocatalyst and also compiles valuable information regarding the photocatalytic treatment of organic polluted wastewater.

Abstract
Graphene oxide/Bi2WO6 (GBW) photocatalyst was synthesized using a hydrothermal and surface deposition method. GBW/starch composite films with different graphene oxide (GO) additions (0, 0.25, 0.5, 0.75, 1 %) were prepared using a casting method. The GBW photocatalyst and composite starch film were characterized using X-ray diffractometry, X-ray photoelectron spectroscopy, Ultraviolet-visible diffuse reflectance spectroscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, synchronous thermal analyzer, and the capacity of photocatalytic degradation of ethylene under visible light was evaluated. The results showed that GBW strengthens the mechanical properties, water vapor resistance and thermal stability of the composite film. Proper introduction of GO can refine lattice size, reduce bandgap and enhance visible light absorption. When the addition of GO was 0.5 %, GBW/starch composite film showed the strongest visible light degradation activity for ethylene, and the rate constant K' was 9.91 × 10-4 min-1, 4.4 times that of pure Bi2WO6. The composite film also had good recycling performance.

Abstract
Water and soil contamination has become unavoidable due to the enormous usage of pesticides in agriculture. Among the pesticides, monocrotophos (MCP), a popular and largely used pesticide, is extremely toxic to birds and humans, which is easily leached into the environment. Therefore, establishment of a green tactic to clean the environment from such hazard is very essential. Herein, we have developed a novel ternary nanocomposite, Ag3PO4/polyaniline@g-C3N4 with enhanced electron-hole separation efficiency, a condition which is very much required for any photocatalyst. The nanocomposite was one-pot synthesized by a simple and economical hydrothermal method. The strategically modulated band gaps of the nanocomposite help harvest the sunlight efficaciously for the robust degradation of MCP (99.6%). It has been found that the active species involved in the photo-cleaning process are OH· and O2·-. A suitable reaction mechanism has been proposed and discussed. Analytical techniques, which include energy-dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), elemental mapping analysis, high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy (UV-DRS), and X-ray diffraction (XRD), were used to characterize the synthesized nanocomposite. This nano-photocatalyst, which is simple, stable, and reusable, certainly has potential applications in soil contamination remediation, sewage treatments, and other environment decontaminations. Also, a study of this kind offers more strategic plans for the production of clean energy (hydrogen) by solar-driven water splitting.

Abstract
To overcome the practical application limitations of Ag3PO4 such as photocorrosion and relatively low efficiency of photogenerated carrier seperation, Ag3PO4 particles were loaded onto hydrochar. The particles in the composite had a smaller crystallite size and different phase structure with more edges than pure Ag3PO4 particles. The as-prepared composite catalyst exhibited a different photocatalytic performance for sulfamethoxazole (SMX) degradation when varying the mass ratio of hydrochar and Ag3PO4. In addition to higher SMX degradation efficiency, the composite exhibited much higher TOC degradation efficiency, recycling stability, and less-toxic intermediate production. The composites enhanced visible light response, and accelerated electron transfer and photogenerated carrier separation as well. The addition of H2O2 to the photocatalytic system enhanced the photocatalytic activity of the composite catalyst. According to a mechanistic examination, the hole (h+) is the dominant reactive species for SMX degradation. This study provides new insight into high-efficiency, low cost, and easily prepared photocatalysts for pollution removal from water. To overcome the practical application limitations of Ag3PO4 such as photocorrosion and relatively low efficiency of photogenerated carrier seperation, Ag3PO4 particles were loaded onto hydrochar.![]()
