A green strategy to synthesize Ag/Ag3PO4/chitosan composite photocatalysts and their photocatalytic degradation performance under visible-light irradiation

Magnetic CoFe1.95Y0.05O4-Decorated Ag3PO4 as Superior and Recyclable Photocatalyst for Dye Degradation

“…It is worth noting that Ag 3 PO 4 has the main ability of absorbing light in the UV region, but with minimal absorption of incident light when the wavelength exceeds 500 nm [ 14 ]. To explore the light absorption capacity of the Ag 3 PO 4 /CoFe 1.95 Y 0.05 O 4 nanocomposites, Diffuse Reflectance Spectrum (DRS) tests are conducted and are presented in Figure 3 a, and it can be seen that pure Ag 3 PO 4 has the ability to absorb light in both the UV and visible regions, with a majority of the absorption occurring in the UV region.…”

“…One of the most promising photocatalysts is silver phosphate (Ag 3 PO 4 ), which has an extremely high photooxidation capacity, a high quantum efficiency of around 90%, and a low band gap of approximately 2.5 eV. As a result, Ag 3 PO 4 has been extensively studied in degrading organic pollutants in water due to its good photocatalytic activity [ 14 , 15 , 16 , 17 ]. Nevertheless, the reported Ag 3 PO 4 usually has a larger particle size and smaller specific surface area, and has a lower stability with prolonged exposure to light, leading to an unsatisfactory photocatalytic activity and stability.…”

“…In order to optimize the photocatalytic properties of Ag 3 PO 4 in practical applications, it is essential to design matrix materials with a smaller particle size and long-term stability. An effective approach to achieve this is to create a heterojunction structure by coupling Ag 3 PO 4 with another substance [ 14 , 16 , 18 ]. The heterojunction structure can facilitate the separation of photogenerated electrons and holes, preventing electron–hole recombination and improving the stability of Ag 3 PO 4 .…”
