| Popis: | Recently, hybrids of layered MoS 2 are highly encouraged to handle the puzzles, taken by the weakness of two-dimensional (2D) transition metal dichalcogenides (TMDC), including low conductivity and lack of active edge sites. Considering the merits of zero-dimensional (0D) nanomaterials, the emerging heterostructures based on 0D Au nanoparticles and 2D MoS 2 nanosheets (MoS 2 -NSs) are successfully obtained via a spontaneously reduced process with the addition of HAuCl 4 in exfoliated MoS 2 -NSs aqueous dispersions. Significantly, with the combination of high conductivity rate and large active surface, the synthetic effect results in a diversity of improved properties of 0D-2D heterostructures, not only exhibiting improved stability, but also remarkably enhancing the selectivity and sensitivity for electrochemically simultaneous detections of dopamine, ascorbic acid, uric acid, and nitrite. Our current achievements of 0D-2D heterostructures contribute fresh ideas to the overall development of more advanced future TMDC based sensors. |
