Facile Synthesis of Ag3PO4 Photocatalyst with Varied Ammonia Concentration and Its Photocatalytic Activities For Dye Removal

“…The [Ag(NH3)2] + complex was created by the interaction of Ag + and ammonia in the solution which was favorable to decrease the reaction rate and thus easily produced more well-structured particle or hindered the agglomeration. Moreover, these properties could increase the surface area and enhance the photocatalytic activity of the catalyst [22][23][24][25]. The high surface area could provide the more active site for photodecomposition of Rhodamine B.…”

“…These can suppress the dyes adsorption due to the repulsion of catalyst and dyes [38]. Conversely, although in the appropriate base condition where OHˉ ions are able to produce the photo-generated OH• radicals through hole and electron reaction mechanism [39][40], in the higher or extreme base condition, the photocatalytic activity decreases due to the reduction of Ag + ions to Ag 0 [23]. It could be considered that the optimum pH was achieved at a neutral condition or a pH of 7.…”

Room-temperature synthesis of Ag3PO4 nanoparticles with the assistance of trisodium citrate for photocatalytic dye degradation

“…Therefore, the focus is on the synthesis of small-size (large specific surface area) Ag 3 PO 4 particles to improve the photocatalytic activity. 7,8 Although several factors affect the photodegradation performance, such as the uniform morphology of Ag 3 PO 4 NPs with smooth surface, Ag 3 PO 4 NPs with sharp corners and edges exhibit superior photocatalytic activity due to the presence of planes with high surface energies. 9 Moreover, semiconductor coupling and surface modification have also been adopted to enhance the photocatalytic performance through the avoidance of electron–hole recombination.…”

“…13 Ag 3 PO 4 NPs in sizes ranging from 40 to 50 nm were prepared by Liu et al using different amounts of PO 4 3− anions. 7 In our previous work, we obtained uniform Ag 3 PO 4 microcrystals in the size range of 200 nm to 1000 nm by changing the ratio of H 2 O and ethylene glycol ( E g ) in the organic solvent. 14 However, this method is not suitable to prepare smaller NPs with sizes below 200 nm.…”
