Massively synthesizable nickel-doped 1T-MoS₂ nanosheet catalyst as an efficient tri-functional catalyst.

ABSTRACT: In this study, a nickel (Ni)-doped 1T-MoS₂ catalyst, an efficient tri-functional hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR) catalyst, was massively synthesized at high pressure (over 15 bar). The morphology, crystal structure, and chemical and optical properties of the Ni-doped 1T-MoS₂ nanosheet catalyst were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and ring rotating disk electrodes (RRDE), and the OER/ORR properties were characterized using lithium-air cells. Our results confirmed that highly pure, uniform, monolayer Ni-doped 1T-MoS₂ can be successfully prepared. The as-prepared catalysts exhibited excellent electroc
