Abstract:MoS2@ZnO nanoheterostructures were synthesized by electrospark erosion of zinc granules in a hydrogen peroxide solution and simultaneous addition of MoS2 nanostructured powder into the reaction zone. The morphology, size of the crystallites, as well as elemental and phase composition of the prepared structures, were examined using transmission electron microscopy and X-ray diffraction analysis. It was found that the synthesized products represent heterostructures containing MoS2 nanoparticles formed on ZnO nan… Show more
“…56 This obviously shows that the combination of ZnO and MoS 2 is beneficial for reducing the resistance of the nanocomposite, and improving the transfer efficiency of photogenerated carriers. 49 Moreover, the instantaneous photocurrent response of MZ-15 in Fig. 8b surpasses that of ZnO and MoS 2 , indicating that MZ-15 has the lowest photogenerated electron–hole recombination rate.…”

“…48 The XRD pattern of the MoS 2 /ZnO heterostructure exhibited characteristic peaks from both MoS 2 and ZnO, indicating that the introduction of MoS 2 into ZnO did not change the crystal structure of ZnO. 49 However, the diffraction peaks of MoS 2 Scheme 1 Illustration for the fabrication of MoS 2 /ZnO composites. were relatively weak, which can be attributed to the low content of MoS 2 and its high dispersion within the sample.…”

“…The improved efficiencies may be because structural defects 87,88 in the heterostructure provide more trapping sites for the electrons and delay the recombination process of electron (e À )-hole (h + ) pairs and ultimately trigger the degradation of organic dyes. 89 The wrapped and curved nanosheets provide a large surface area and interspaces which is very suitable for an efficient catalytic reaction. The interaction between MoS 2 nanosheets and ZnO induces charge transfer from ZnO to MoS 2 and increases the efficiency of charge separation of the photogenerated electron-hole pairs.…”
The heterostructure catalyst MoS2-ZnO possesses binary properties and provides a novel platform for the remediation of environmental as well as health issues.
