Fabrication of MIL-53(Fe)/Ag₃PO₄ cooperative photoreduction of Ag⁰ particles with outstanding efficiency for photodriven H₂ evolution and pollutant degradation

Abstract

The novel heterostructure photocatalyst includes photoreduction of Ag0 loaded MIL-53(Fe)/Ag3PO4 (MFAAx) composites were designed and successfully synthesized via hydrothermal with deposition and photoreduction method. Then the physicochemical and optical properties...

Ag/AgX (X = Cl, Br, or I) Nanocomposite Loaded on Ag3PO4 Tetrapods as a Photocatalyst for the Degradation of Contaminants

“…This proves that Ag enhances the light absorption property; furthermore, it promotes the transfer of charge. , In addition, the lifetimes of the various samples are estimated by fitting the time–decay curves using the following function f ( t ) = A + A 1 × exp ( − t τ 1 ) + A 2 × exp ( − t τ 2 ) + A 3 × exp ( − t τ 3 ) where A 1 , A 2 , and A 3 are regarded as the corresponding amplitudes, as well as τ 1 , τ 2 , and τ 3 are decay constant. The average lifetime is calculated as equation τ = A 1 τ 1 2 + A 2 τ 2 2 + A 3 τ 3 2 A 1 τ 1 + A 2 τ 2 + A 3 τ 3 Figure S6 and the calculation results in Table S1 exhibit that the formation of heterojunction between Ag 3 PO 4 and AgX as well as the modification of Ag markedly strengthens the lifetime of electrons. The sample IAA-10 has the highest τ value (15.33 ns), which is 2.95 times higher than that of APO (5.19 ns).…”
