Information Content Entity
Metal nanoclusters (M NCs ) based on gold as core and silver as shell, abbreviated as Ag%40Au NCs , were electrostatically associated with functionalized semiconducting MoS 2 nanosheets, abbreviated as f-MoS 2 . The realization of the Ag%40Au NCs /f-MoS 2 ensemble was manifested by UV–vis and photoluminescence titration assays, while its morphology was evidenced by high-angle annular dark-field STEM imaging coupled with EDX analyses. Photoinduced intra-ensemble charge-transfer phenomena were witnessed and attributed to the suppression and concomitant shift of Ag%40Au NC photoluminescence by incremental additions of f-MoS 2 . The Ag%40Au NCs /f-MoS 2 was employed as RhB photodegradation catalyst for wastewater purification from organic pollutant dyes. The production of highly oxidant radicals from the photogenerated electron-hole pairs within Ag%40Au NCs /f-MoS 2 were found to be the main reactive species, while the holes left on Ag%40Au NCs attacked RhB, as evidenced by the disappearance of the characteristic absorption peak. The photocatalytic reaction by the ensemble followed fast kinetics as compared with bare Ag%40Au NCs or individual Au NCs and Ag NCs . © 2019 Elsevier Ltd
