Exploring earth-abundant in expensive highly active electrocatalysts for hydrogen evolution reaction (HER) is crucial for energy harvesting and effective overall water splitting. In this regard, flower-like VS2 microspheres anchored on Ti3C2Tx MXene hybrid heterostructure are successfully fabricated by simple one step hydrothermal process and used as electrocatalysts for HER. Beneficial from the synergetic and strong coupling effect between VS2 microspheres and Ti3C2Tx the synthesized hybrid heterostructure ensures numerous active sites, displayed high conductivity and excellent electrocatalytic performance. Notably, the optimized VS2/Ti3C2Tx hybrid delivers a superior HER activity with overpotential of 123 mV and a Tafel value of 107 mV dec−1 in alkaline media. Furthermore, the hybrid catalysts showed outstanding durability over 100 h for HER in alkaline medium. © 2026 Elsevier B.V.
