Ultrafast and high efficiency photodegradation of dyes under visible light by Au nanocluster-promoted Zn_0.5Cd_0.5S nanorods

Abstract

Plasmon-mediated photocatalysts composed of Au nanoclusters and ultrathin Zn0.5Cd0.5S nanorods (Au/ZCS NRs) were synthesized by a facile method. All Au/ZCS samples present significant improvement for dyes degradation under visible light....

One-pot hydrothermal synthesis of a carbon quantum dot/CaFe2O4 hybrid nanocomposite for carcinogenic Congo red dye degradation

“…Scientists have subsequently been searching for ways to remove this lethal pollutant from water that represents a serious threat to human health and the environment. 9,10 Several methods have been employed to reduce high dye concentrations in industrial effluents, including adsorption, 11,12 occulation, chemical oxidation, electrochemistry and membrane ltration processes. [13][14][15][16][17] All types of physiochemical processes have limitations due to the incomplete removal of organic dyes, and their being time-consuming and high cost.…”
