Enhanced hydrogen desorption via charge transfer in Pt Nanoclusters/ReS2 hybrid electrocatalyst for efficient hydrogen evolution reaction

Recently, there has been a rising demand for hybrid catalysts with heterojunctions between two catalytic materials. In particular, hybrid materials based on Pt and transition metal dichalcogenides (TMDCs) have been the focus for improving electrocatalysts. However, finding a TMDC support to ensure the long-term stability of Pt/TMDC hybrid catalysts with high activity remains a challenge. In this paper, we present a hybrid electrocatalyst comprising ReS2 nanoflowers and Pt nanoclusters (NCs) for efficient hydrogen evolution reaction (HER). The hybrid catalyst enhanced hydrogen desorption via charge transfer from Pt to ReS2, demonstrating good HER activity with outstanding durability and a low overpotential (20 mV at 10 mA cm−2) compared with conventional Pt/C catalysts. •Facile and quick synthesis of ReS2 nanosheets by microwave-assisted hydrothermal method.•Synthesizing Pt nanoclusters on ReS2 nanosheets as a hybrid HER catalyst system.•Charge transfer from Pt nanoclusters to RseS2 nanosheets for enhancing H desorption.•Enhanced HER performance of Pt/ReS2 hybrid catalyst compared with conventional Pt/C.
