“…Using the calculation of direct transition, the band gap energy of 2.39, 2.41, 2.46, 2.45 eV were found at the samples of Ag3PO4, Ag3PO4-0.05, Ag3PO4-0.15, and Ag3PO4-0.30, respectively (Table 1). It was also similar to the previous re- [20][21]. Therefore, these the band gap energies might not be the main reason for the enhanced photocatalytic activity.…”

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. dye removal. Silver orthophosphate has the band gap energy of 2.36 eV, that can absorb solar energy shorter than ~530 nm [1-6], possess stronger photo-oxidative capability than the previous photocatalyst [7-9], generating O2 from water splitting with a quantum efficiency nearly 90% in visible light irradiation [10]. In order to improve its photocatalytic activity in the visible light region, many approaches have been performed especially in catalyst fabrication design

“…The silver phosphates were synthesized using simple coprecipitation of AgNO3 and Na2HPO4.12H2O [18] under mangosteen peel extract solution. To preparing the mangosteen peel extracts, fresh mangosteen peel was washed with water and dried in the open air for 3 days.…”

“…Modification of Ag3PO4 into composite photocatalysts has also significantly improved photocatalytic activity. Generating electron excitation could effectively be facilitated in a hybrid photocatalyst [18], p-n heterojunction [19], and Zscheme mechanism [20] which can boost the photocatalytic ability. The formation of g-C3N4/Ag3PO4 hybrid can maintain the Ag3PO4 from dissolution in water [21].…”

The synthesis of silver phosphate (Ag3PO4) photocatalyst has been widely developed for organic pollutant degradation. However, the large particle of this photocatalyst limits the photocatalytic activity. The smaller particle size of the Ag3PO4 photocatalyst was successfully prepared using the starting material of AgNO3 and Na2HPO4.12H2O under mangosteen peel extract solution. The starting materials were dissolved in mangosteen peel extract solutions prepared at the concentration of 1% (w/v). The reaction of silver nitrate and phosphate solution was conducted at room temperature. The samples of pristine Ag3PO4 and Ag3PO4 prepared under mangosteen peel extract were studied using XRD, DRS, SEM, BET, and FTIR. All photocatalytic activities were evaluated using Rhodamine B photooxidation under blue light irradiation (LED, 3 Watt). The results showed that the mangosteen peel extract significantly decreased the particle size, lowered the bandgap energy from 2.12 to 2.00 eV, and increased the crystallinity of Ag3PO4. The interaction of xanthones from mangosteen peel extract solution with silver ion might affect the growth particle of Ag3PO4, and inhibit the agglomeration leading to small particle size, more uniform distribution, high crystallinity, and low bandgap energy. These properties enhanced the photocatalytic activity up to 2.9 times higher compared to the sample without the treatment of mangosteen peel extract.
