Atomically Dispersed Sn on Core-Shell MoS₂ Nanoreactors as Mott-Schottky Phase Junctions for Efficient Electrocatalytic Hydrogen Evolution.

ABSTRACT: The electrocatalytic hydrogen evolution reaction (HER) plays a pivotal role in electrochemical energy conversion and storage. However, traditional HER catalysts still face significant challenges, including limited activity, poor acid resistance, and high costs. To address these issues, a hollow core-shell structured 2H@1T-MoS₂-Sn₁ nanoreactor is designed for acidic HER, where Sn single atoms are anchored on the shell of 2H@1T-MoS₂ Mott-Schottky phase junction. The 2H@1T-MoS₂-Sn₁ catalyst demonstrates exceptional HER performance, achieving an ultralow overpotential of 9 mV at 10 mA cm^-2 and a Tafel slope of 16.3 mV dec^-1 in acidic media-the best performance reported to date among MoS₂-based electrocataly
