Phosphorus-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.
متن کاملRecent advances in unveiling active sites in molybdenum sulfide-based electrocatalysts for the hydrogen evolution reaction
Hydrogen has received significant attention as a promising future energy carrier due to its high energy density and environmentally friendly nature. In particular, the electrocatalytic generation of hydrogen fuel is highly desirable to replace current fossil fuel-dependent hydrogen production methods. However, to achieve widespread implementation of electrocatalytic hydrogen production technolo...
متن کاملMetal diselenide nanoparticles as highly active and stable electrocatalysts for the hydrogen evolution reaction.
In this communication, nickel diselenide (NiSe2) nanoparticles are synthesized by a facile and low-cost hydrothermal method. The synthesis method can be extended to other metal diselenides as well. The electrode made of NiSe2 exhibits superior electrocatalytic activity in the hydrogen evolution reaction (HER). A low Tafel slope of 31.1 mV per decade is achieved for NiSe2, which is comparable to...
متن کاملStructure dependent active sites of NixSy as electrocatalysts for hydrogen evolution reaction.
Structure effects of NiS and Ni3S2 nanoparticles were investigated for their electrocatalytic activity in the hydrogen evolution reaction in both acid and alkaline media. Owing to the different atomic configurations and crystalline structures, there is a hydrogen adsorption energy difference, which induces a difference in the activity. From density functional theory calculations and experimenta...
متن کاملEdge-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 ...
