Edge-exposed MoS2 nano-assembled structures as efficient electrocatalysts for hydrogen evolution reaction.
Edge-exposed MoS2 nano-assembled structures are designed for high hydrogen evolution reaction activity and long term stability. The number of sulfur edge sites of nano-assembled spheres and sheets is confirmed by Raman spectroscopy and EXAFS analysis. By controlling the MoS2 morphology with the formation of nano-assembled spheres with the assembly of small-size fragments of MoS2, the resulting ...
متن کاملTwo-Dimensional Material Molybdenum Disulfides as Electrocatalysts for Hydrogen Evolution
Recently, transition metal dichalcogenides (TMDs), represented by MoS2, have been proven to be a fascinating new class of electrocatalysts in hydrogen evolution reaction (HER). The rich chemical activities, combined with several strategies to regulate its morphologies and electronic properties, make MoS2 very attractive for understanding the fundamentals of electrocatalysis. In this review, rec...
متن کاملSulfur poisoning of emergent and current electrocatalysts: vulnerability of MoS2, and direct correlation to Pt hydrogen evolution reaction kinetics.
The recent surge in interest in the utilisation of transition metal dichalcogenides for the hydrogen evolution reaction (HER), as well as the long-standing problem of sulfur poisoning suffered by the established Pt HER electrocatalyst, motivated us to examine the impacts of sulfur poisoning on both emergent and current electrocatalysts. Through a comparative study between MoS2 and Pt/C on the e...
متن کاملHighly porous non-precious bimetallic electrocatalysts for efficient hydrogen evolution
A robust and efficient non-precious metal catalyst for hydrogen evolution reaction is one of the key components for carbon dioxide-free hydrogen production. Here we report that a hierarchical nanoporous copper-titanium bimetallic electrocatalyst is able to produce hydrogen from water under a mild overpotential at more than twice the rate of state-of-the-art carbon-supported platinum catalyst. A...
متن کاملPhosphorus-doped CoS2 nanosheet arrays as ultra-efficient electrocatalysts for the hydrogen evolution reaction.
In this communication, we, for the first time, prepared phosphorus-doped cobalt disulfide nanosheets as highly advanced electrocatalysts for the hydrogen evolution reaction. It was demonstrated that P doping could significantly enhance the electrocatalytic performance of CoS2 nanosheets in terms of onset overpotential, Tafel slope, exchange current density, and stability.
