Abstract

The highly active photocatalyst of Ag3PO4 could be synthesized under ammonia solution using the facile co-precipitation method with the starting material of AgNO3 and Na2HPO4.12H2O.  The variation of ammonia concentration was designed at 0.00, 0.05, 0.15, and 0.30 M. The products were characterized using X-ray diffraction, UV-diffuse reflectance spectroscopy, and scanning electron microscopy. The photocatalytic activities were evaluated using the Rhodamine B degradation under blue light irradiation.  The effect of calcination, pH condition, and visible light source irradiation was carried out in the experiment. The highest photocatalytic activity was found in the sample prepared using the addition of ammonia solution at the concentration of 0.05 M. This photocatalytic activity was 4.13 times higher compared to the Ag3PO4 prepared without the ammonia. The effective condition of photocatalytic activity was achieved at the sample prepared without calcination, degradation at pH of 7 and under blue light irradiation.

Abstract

The improvement of Ag3PO4 photocatalytic activity was successful by incorporating tetrachloroaurate(III) (AuCl4−)  and metallic Au on the surface of Ag3PO4. The photocatalysts were synthesized using the coprecipitation and chemisorption method. Coprecipitation of Ag3PO4 was carried out under ethanol-water solution using the starting material of AgNO3 and Na2HPO4.12H2O. AuCl4− ion and metallic Au were incorporated on the surface of Ag3PO4 using a chemisorption method under auric acid solution. The photocatalysts were characterized using XRD, DRS, SEM, and XPS. The AuCl4− ion and metallic Au were simultaneously incorporated on the Ag3PO4 surface. The high photocatalytic activity might be caused by increasing the separation of hole and electron due to capturing photogenerated electrons by metallic Au and Au(III) as electron acceptors.

Abstract

This study investigates the synthesis and photocatalytic performance of BiVO4-Nigella Sativa/g-C3N4 composites for the degradation of methylene blue dye. The composites were synthesized using a coprecipitation method and characterized through various techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), UV-Vis diffuse reflectance spectroscopy (DRS), Brunauer-Emmett-Teller (BET) surface area analysis, and scanning electron microscopy (SEM) to determine their crystal structure, chemical composition, morphology, adsorption and photocatalytic abilities. A variation of mass ratios of BiVO4 to g-C3N4 of 1:2, 1:3, and 1:4 was used in this investigation. The photocatalytic test results indicated that the composite with a mass ratio of 1:2 achieved the highest methylene blue degradation, reaching 91.73%, which was primarily attributed to an adsorption activity of 81.12% and a photocatalytic degradation of 10.60%. The photocatalytic activity was significantly enhanced under alkaline conditions, particularly at pH levels between 9 and 10, which facilitated the formation of reactive oxygen species (ROS). The study highlights the synergistic effects of the BiVO4 and g-C3N4 combination, which promotes efficient charge transfer, reduces electron-hole recombination, and expands light absorption due to a decrease in the effective bandgap energy. Overall, the findings indicate that BiVO4-Nigella Sativa/g-C3N4 composites have considerable potential for application in wastewater treatment, particularly for the remediation of organic dye pollutants.
