Constructing Sulfur Vacancy-Rich NiCo₂S₄@MoS₂ Core@shell Heterostructure via Interface Engineering for Enhanced HER Electrocatalysis.

ABSTRACT: The rational design of heterointerfaces with optimized charge dynamics and defect engineering remains pivotal for developing advanced non-noble metal-based electrocatalysts for water splitting. A comparative study of NiCo₂S₄-MoS₂ heterostructures was conducted to elucidate the impact of interfacial architecture and defect engineering on hydrogen evolution reaction (HER) performance. A core@shell NiCo₂S₄@MoS₂ heterostructure was synthesized via a facile hydrothermal growth method, inducing lattice distortion and strong interfacial coupling, while supported NiCo₂S₄/MoS₂ heterostructures were prepared by ultrasonic-assisted deposition. A detailed structural and spectroscopic characterization and
