One-Step Hydrothermal Fabrication of Three-dimensional MoS₂ Nanoflower using Polypyrrole as Template for Efficient Hydrogen Evolution Reaction.

ABSTRACT: Herein, a facile and cost-effective strategy for hydrothermal synthesis of three-dimensional (3D) MoS₂ with adequate active edge sites and advanced hydrogen evolution reaction (HER) performance using polypyrrole (PPy) as template is reported. The MoS₂ is first thermally nucleated using hexaammonium heptamolybdate tetrahydrate (NH₄)₆Mo₇O₂₄·4H₂O and thiourea as precursor in the presence of PPy, and then they are further annealed to remove PPy at higher temperature to generate 3D MoS₂-P. Morphology and composition characterizations reveal that the 3D MoS₂-P exhibits a nanoflower morphology. It presents larger stretched "thin folding leaves" and higher mesoporous volume of 0.608 cm³ g<
