Facile fabrication of conductive MoS 2 thin films by sonication in hot water and evaluation of their electrocatalytic performance in the hydrogen evolution reaction

Molybdenum disulfide (MoS₂) has long been used in catalysis and is a promising material for energy conversion devices. In order to utilize MoS₂ in electrocatalytic applications, it needs to be sufficiently conductive. Even though a metallic 1T phase of MoS₂ exists, its exfoliation process is expensive and difficult to scale because it involves hazardous materials and procedures, limiting its practical applications. We have previously reported …
