Summary: In recent years, there has been an increasing demand for hybrid catalysts with heterojunctions between two catalytic materials. Pt and transition metal dichalcogenides (TMDCs) have been the focus for improving electrocatalysts. However, finding a TMDC support for long-term stability of Pt/TMDC hybrid catalysts with high activity remains a challenge. In this study, a hybrid electrocatalyst consisting of ReS2 nanoflowers and Pt nanoclusters (NCs) was presented for efficient hydrogen evolution reaction (HER). The hybrid catalyst exhibited enhanced hydrogen desorption through charge transfer from Pt to ReS2, demonstrating good HER activity, excellent durability, and a low overpotential (20 mV at 10 mA cm-2) compared to conventional Pt/C catalysts.
