Structure and Optical Properties of Some Layered Two-Dimensional Transition- Metal Dichalcogenides: Molybdenum Disulfide, Molybdenum Diselenide, and Tungsten Diselenide
This paper presents a systematic study of intrinsic characteristics of layered two-dimensional transitionmetal dichalcogenides, with a focus on molybdenum disulfide, molybdenum diselenide, and tungsten diselenide. Recent advances in high-resolution transmission electron microscopy (HRTEM) have made atomic-resolution imaging possible, thus enabling one to closely examine real and reciprocal spac...
متن کاملSynthesis of Supported Pt Alloy three Dimensional Rhombus Shapes Nanoparticles for Oxygen Reduction Reaction
In this study PtFeCo ternary alloys nanoparticles of three dimentional (3D) rhombus shapes dispersed on graphene nanosheets (PtFeCo/Gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (ORR) in polymer-electrolyte fuel cells. A combination of analytical techniques including powder X-ray diffraction, X-ray photoelectron spectra, inductively coupled plasma-...
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 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 کاملThree-dimensional Nitrogen-Doped Graphene Supported Molybdenum Disulfide Nanoparticles as an Advanced Catalyst for Hydrogen Evolution Reaction
An efficient three-dimensional (3D) hybrid material of nitrogen-doped graphene sheets (N-RGO) supporting molybdenum disulfide (MoS(2)) nanoparticles with high-performance electrocatalytic activity for hydrogen evolution reaction (HER) is fabricated by using a facile hydrothermal route. Comprehensive microscopic and spectroscopic characterizations confirm the resulting hybrid material possesses ...
