Scalable Synthesis of Pt Nanoflowers on Solution-Processed MoS₂ Thin Film for Efficient Hydrogen Evolution Reaction.

ABSTRACT: Nanostructuring of Pt nanocatalysts increases the surface-to-volume ratio, thus enabling efficient usage of Pt for hydrogen evolution reaction (HER). Direct electrochemical reduction of Pt on the electrode can produce nanostructured Pt catalysts, which has been time-consuming for the conventional colloidal synthesis. However, carbon-based growth templates commonly used to create Pt nanoparticles offer limited control over morphologies and HER performance. Herein, a facile electrochemical synthesis of Pt nanoflowers (NFs) with well-defined petals is presented. Semiconducting MoS₂ nanosheets are solution processed into a film on a carbon paper (CP) to synthesize Pt NFs upon reduction of Pt precursor. The Pt NFs show higher HER activities than spherical or spiky Pt nanoparticles be
