Zinc oxysulfide ternary alloy nanocrystals: A bandgap modulated photocatalyst

摘要

Herein, we report a green economic route for the synthesis of a series of Zinc Oxysulfide (ZOS) (ZnO_(1_x)S_x; 0≤ x ≥ 1; x = Sulfur) alloys nanoparticles. The crystallographic features of ZnO, ZOS, and ZnS confirmed by X-Ray Diffraction and validated by Transmission Electron Microscopy reveal the variation of lattice spacing in binary and ternary compositions with homogenous elemental distribution. The photocatalytic analysis of ZOS (0.4) is performed and compared with Degussa P25 to ascertain its photocatalytic activity against methyl orange under irradiation of 365 nm UV-Vis light. A bandgap of 2.7 eV for ZOS (0.4) aptly establishes its prospects for sunlight driven photocatalysis.
