“…Silver nanoparticles (AgNPs) as a popular noble metal were widely used to fabricate Ag/g-C 3 N 4 nanocomposite by photodeposition. 12,15,16 Many researchers found the similar phenomenon that the modication of silver nanoparticles could effectively enhanced the photocatalytic activity of g-C 3 N 4 due to the improved charge separation efficiency.…”

Membrane fouling is still the main obstacle for the wider application of membrane processes. In this study, different amounts of silver modified graphitic carbon nitride (Ag/g-C 3 N 4 ) were firstly introduced into polyethersulfone (PES) membranes by blending via a phase-inversion method. The impacts of Ag/g-C 3 N 4 addition on the membrane morphology, filtration and photocatalysis antifouling properties of Ag/g-C 3 N 4 /PES nanocomposite membranes were systematically studied. The results illustrated that the addition of Ag/g-C 3 N 4 could make the finger-like voids in Ag/g-C 3 N 4 nanocomposite membrane longer and wider, increasing the hydrophilicity and filtration property of the nanocomposite membrane. Also the addition of Ag/g-C 3 N 4 nanosheets could endow the nanocomposite membranes with excellent antibacterial, photocatalytic dye degradation and antifouling properties under visible light irradiation.

“…Nevertheless, the photocatalytic performance of g-C 3 N 4 is restricted by the low quantum efficiency originated from its slow charge mobility and fast recombination of photogenerated electron-hole pairs. To overcome the above mentioned disadvantages, various strategies have been developed to improve the photocatalytic performance of g-C 3 N 4 , such as constructing heterojunctions [11,12], doping with non-metal [13][14][15][16] or noble metal [17], modifying with inorganic or organic semiconductors [18]. The photocatalytic activity of semiconductors could be significantly improved by modifying with noble metal (Ag, Au and Pt), resulting from the surface plasmon resonance (SPR) effect.…”

“…A broad intensive band with several weak peaks ranging from 400 to 600 nm is observed and ascribed to charge-transfer transitions between valance and conduction band, the surface-defect like oxygen vacancies generated from the fast growth rate, and different valence states of bismuth ions in Bi 12 O 17 Cl 2 [10,12]. The existence of deposited Ag can inhibit the radiative recombination of generated charge carriers [32]. Accordingly, the emission band intensity of the sample AB4 is weaker than those of samples AB0 and AB8, suggesting that the presence of appropriate amount of Ag is crucial to the efficient separation of photogenerated charge carries.…”

a b s t r a c tIn this investigation, novel Ag/Bi 12 O 17 Cl 2 plasmonic composites with different Ag contents were constructed through a solvothermal and subsequent photoreduction route and fully characterized by a collection of analytical techniques. Spectroscopic results confirmed the presence and uniform dispersion of Ag nanoparticles on the 2D nanosheets of Bi 12 O 17 Cl 2 . The Ag content in composites exerted considerable influence on the extension of light-adsorption range and the enlargement of specific surface areas. The photocatalytic abilities of these Ag/Bi 12 O 17 Cl 2 composites were evaluated toward the degradation of rhodamine B (RhB) and 2,4-dichlorophenol (2,4-DCP) under the visible-light irradiation. The results demonstrated that the Ag/Bi 12 O 17 Cl 2 composites showed much higher photocatalytic efficiencies than that of pure Bi 12 O 17 Cl 2 , especially the sample with an optimal Ag content showing the best photocatalytic behavior among all tested samples. The remarkable enhancement of Ag/Bi 12 O 17 Cl 2 photocatalytic efficiency could be mainly attributed to the efficient charge separation that was induced by the localized surface plasmon resonance effect of metallic Ag, strong visible-light adsorption and the favorable morphology with enlarged specific surface areas. Eventually, the photocatalysis mechanism over Ag/Bi 12 O 17 Cl 2 composites was preliminarily proposed on the base of reactive species trapping experiments.
