Enhanced visible-light-driven photocatalytic performance of Ag/AgGaO2 metal semiconductor heterostructures

Shell Thickness Dependence of the Plasmon-Induced Hot-Electron Injection Process in Au@CdS Core–Shell Nanocrystals

“…Metal–semiconductor nanoheterostructures − have emerged as one of the leading materials in photocatalysts because nanometal’s local surface plasmon resonance (LSPR) − enhances the utilization of solar energy, and the metal–semiconductor contact interface accelerates photogenerated carriers’ separation and delocalization. Among these materials, the metal@semiconductor core–shell nanostructure − becomes one of the most promising functional structures.…”

Fabrication of metal/semiconductor hybrid Ag/AgInO2 nanocomposites with enhanced visible-light-driven photocatalytic properties

“…The XRD pattern of AgInO 2 shows typical diffraction peaks 2q located at 14.0 , 28.3 , 32.9 , 36.9 , 50.3 , 56.1 , 58.6 , 64.0 , and 66.6 , corresponding to (003), (006), (012), (104), (018), (110), (0012), (116), and (202), respectively, which are well-indexed to the rhombohedral structure of AgInO 2 with JCPDS no. 21 besides the peaks of AgInO 2 , the major diffraction peaks of the metal Ag (JCPDS no. 65-2871) are also present.…”

“…Experimental details have been previously published. 21,23 Briey, the photocatalytic reaction was carried out in an open reactor containing 200 mL of MB solution at a concentration of 10 mg L À1 and 0.2 g catalyst. Prior to irradiation, the solution suspension was magnetically stirred for 30 min to ensure adsorption/desorption equilibrium between the samples and MB solution in the dark.…”

“…[12][13][14][15][16][17][18] Aer this, Zhang et al mentioned that despite the importance of Ag/semiconductor composites in heterogeneous photocatalysis, the interplay between Ag and semiconductors still remained largely unexplored. 19 In our previous studies, 20,21 our group has reported Ag/AgAlO 2 composites and Ag/AgGaO 2 metal-semiconductor heterostructures with the enhanced photocatalytic activities under visible-light irradiation. Based on the abovementioned studies, AgInO 2 , which belongs to the family of AgMO 2 (M ¼ Al, Ga, and In), is another promising Ag-based photocatalyst containing d 10 metal ion electronic conguration of Ag + ; however, to the best of our knowledge, to date, no study has been reported on the preparation of the Ag/AgInO 2 nanocomposites as an efficient visiblelight-responsive photocatalyst for organic dye decomposition.…”

Shape tailoring of AgBr microstructures: effect of the cations of different bromide sources and applied surfactants

“…7 Because of the low stability of the semiconductors mentioned above, other Ag-based photocatalytic materials have been investigated, such as Ag 3 PO 4 , 8 Ag 2 SO 4 , 9 Ag 2 CO 3 , 10 and delafossite-type Ag-based semiconductors (e.g., AgGaO 2 (ref. 11) or AgAlO 2 (ref. 12)).…”
