二硫化钼具有独特的各向异性，多型性和丰富性，使其成为多种催化，电化学和摩擦学应用中具有独特用途的材料。据报道，通过水热合成，由良性试剂大规模生产了高表面积，可任选负载的，具有拒气性的金属MoS ₂（1T-MoS ₂）。该水热生产的材料已显示出作为电容器和作为电催化剂（例如用于氢释放反应）的出色性能。然而，合成歧义性和样品的错误表征在水热法生产的1T-MoS ₂的报道文献中极为普遍。，这些现象在诸如拉曼光谱，X射线衍射，磁化率和X射线光电子能谱之类的多种分析技术中都会发生。这些疏忽导致对1T-MoS ₂的普遍理解存在重大矛盾。在大多数情况下在文献中它是不清楚是否的MoS ₂或插层（M ^{Ñ +}）_{（1 / Ñ）}沫^III小号_{2 ^-}产生变体。考虑到这种材料在许多前沿应用中的巨大潜力，重要的是要弄清楚文献资料以帮助促进快速发展。在这种情况下，本综述提出了提供清晰明确的合成和分析策略的方法，提出了一种前进的方向。

Critical review: hydrothermal synthesis of 1T-MoS2 – an important route to a promising material

The unique anisotropy, polytypism, and abundance of molybdenum disulfide make it a singularly versatile material for a range of catalytic, electrochemical, and tribological applications. By employing a hydrothermal synthesis, a high surface area, optionally-supported, gas-repellent metallic MoS₂ (1T-MoS₂) has been reported to be produced from benign reagents at scale. This hydrothermally produced material has been shown to exhibit outstanding performance as a capacitor, and as an electrocatalyst (e.g. for the hydrogen evolution reaction). However, synthetic ambiguity and sample mischaracterisations are extremely common within the literature of reports of hydrothermally produced 1T-MoS₂, and these occur across a range of analysis techniques such as Raman spectroscopy, X-ray diffraction, magnetic susceptibility, and X-ray photoelectron spectroscopy. These oversights have led to significant inconsistencies in the prevalent understanding of 1T-MoS₂. In most cases in the literature it is unclear whether MoS₂ or an intercalated (Mⁿ⁺)_(1/n)Mo^IIIS_2⁻ variant is produced. Given the high potential of this material for many cutting-edge applications, it is important to clarify the literature to help facilitate rapid progress. In this context the review presents a way forward, by setting out to provide clear and unambiguous synthetic and analytical strategies.
