Abstract
Excellent photocatalytic activity by highly photo-responsive electron transfer from ZnS–RGO, and RGO acts as an electron reservoir and effectively suppresses charge recombination.
Highlights
ZnS has great potential applications in sensors, catalysis and optical properties
A peak at 161 corresponding to the (001) plane and a small minor hump located at 431 for the (101) planes as shown in Fig. 1a indicate the presence of few-layered graphene sheets, which means that reduced graphene oxide (RGO) sheets have been effectively exfoliated from the raw graphite
The FESEM and transmission electron microscopy (TEM) images of the ZnS–RGO composites show that ZnS nanoparticles are in a cubic/isometric lattice structure decorated on graphene sheets with high crystallinity and fine morphology
Summary
ZnS has great potential applications in sensors, catalysis and optical properties. It haswide emerging applications in optoelectronic devices, light emitting diodes, fuel cells, solar energy conversions, photocatalysis, efficient phosphor inflated panel displays, cathode ray tubes, luminescent materials, piezoelectric materials and thin films of electroluminescent devices[13,14] and has been extensively studied because of its size, shape, and morphology dependent quantum confinement effects.[15]Generally, in order to avoid ZnS nanoparticle agglomeration, synthetic polymers, microgels, mesoporous silicate materials and other organic/surfactant stabilizers are adopted as stabilizing or supporting materials to keep the size of ZnS in the nano-range.
