Abstract

The application of MoS2 depends on the morphology and the mainstream fabrication method is the liquid-phase hydrothermal (LPH) one. In this work, a vapor-phase hydrothermal (VPH) process is designed to prepare molybdenum disulfide (MoS2) nanostructures on the Mo pre-deposited titanium substrate. The process is monitored by observing the morphologies at different time points and the products are characterized systematically. Compared to the traditional LPH process, controllable deposition of MoS2 nanosheets with distinctive nucleation mechanism and morphology as well as strong adhesion with the substrate are achieved. The formation mechanisms are analyzed from the perspective of in situ nucleation in VPH versus dissolution/nucleation/coagulation in LPH. The results provide insights into controllable in situ fabrication of nanostructured coatings.
