Abstract

The growing interest in the development of next generation net zero energy systems has led to the expansion of molybdenum disulphide (MoS2) research in this area. This activity has resulted in a wide range of manufacturing/synthesis methods, controllable morphologies, new composite structures, and multiple energy applications for MoS­2 to date. Therefore, it is of paramount importance to classify and understand the relevant interactions and properties of MoS2, in both the 2H and 1T phases and as part of a carbonaceous composite. In this review, key characterisation techniques are divided into the following categories: morphology, crystal structure, composition, and optical characterisation. The most relevant and accessible characterisation techniques: scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution TEM (HRTEM), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), energy dispersive x-ray spectroscopy (EDS) and Raman spectroscopy are covered in detail and statistically analysed. In this review, major discrepancies regarding MoS2 characterisation in the literature to date and currently debated questions are highlighted. Guidance on collecting and presenting MoS2 characterisation data is suggested, including how to effectively combine multiple material characterisation techniques, attention to the macro and micro sample area analysed, provision of valuable reference samples, and the importance of testing statistics. Additionally, 100 research articles are surveyed to tabulate MoS2 parameters, for ease of access in future experimental and computational comparisons.
