WebTransition metal sulfides have emerged as promising hydrogen evolution reaction (HER) electrocatalysts in acidic media due to high intrinsic activity. They exhibit inferior HER activity in alkaline media, however, owing to the sluggish water dissociation kinetics. Herein, in-plane MoS2/Co9S8 heterostructures WebNov 27, 2024 · Gd@MoS2 single-atom catalysts prepared by a simple laser molecular beam epitaxy (LMBE) method. Significant improvement in catalytic kinetics under AMF excitation (3.9 mT) is demonstrated, yielding a ...

The Origin of High Activity of Amorphous MoS2 in the Hydrogen Evolution …

In this study, we investigated both single-crystalline and polycrystalline 2H-phase monolayer MoS2 samples grown by chemical vapor deposition (CVD) for HER. The former samples (type-I) were grown on sapphire substrates with individual domain size of a few hundred micrometers (refer to ref. 25 for our … See more In order to confirm the role of 2H–1T-phase boundaries in the basal plane of MoS2 in HER, we performed scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) characterizations. … See more Based on the above experimental and theoretical results, we can conclude that both domain boundaries and phase boundaries can serve as active sites in HER. More boundaries, in principle, should offer better … See more WebDec 4, 2024 · Molybdenum disulfide (MoS 2 ) has been recognized as one of the most promising candidates to replace precious Pt for hydrogen evolution reaction (HER) catalysis, due to the natural abundance, low cost, tunable electronic properties, and excellent chemical stability. Although notable processes have been achieved in the past … mary jane home comforters
