The limited intrinsic conductivity of two-dimensional (2D) MoS₂ nanosheets compromises its high electrocatalytic performance. In this work, we develop a facile method of simply dispersing MoS₂ nanosheets into a water-isopropanol solution of high-conducting single-walled carbon nanotubes (SWCNTs) for preparation of MoS₂/SWCNT composites. The SWCNTs in the hybrid system serve as effective electron transport channels among 2D MoS₂ nanosheets and facilitate charge transfer at the catalyst-electrolyte interface. We investigated the influence of SWCNTs ratios on the catalytic activities and obtained a high-performance hybrid catalyst with a low Tafel slope of 40.82 mV/decade and prominent electrochemical durability. The demonstration of our hybrid electrocatalytic system, with its scalable capacity for facile preparation, provides a new pathway to enhance HER activity.
