Optical properties of metal-molybdenum disulfide hybrid nanosheets and their application for enhanced photocatalytic hydrogen evolution.
Limited control over charge recombination between photogenerated charge carriers largely hinders the progress in photocatalysis. Here, we introduce metal nanoparticles (Cr, Ag) to the surface of MoS2 nanosheets by simple synthetic means creating a hybrid metal-MoS2 nanosheet system with well-defined metal/semiconductor interfaces. We demonstrate that this hybrid nanosheet structure is capable o...
متن کاملNear-infrared spatial solitons in heavy metal oxide glasses.
We demonstrate two-dimensional spatial solitons excited by near-infrared picosecond pulses in Kerr-like heavy metal oxide glasses with a nonlinearity one order of magnitude larger than in fused silica. Solitons were obtained at 820 nm owing to the presence of multiphoton absorption, which prevented catastrophic collapse.
متن کاملSemimetallic molybdenum disulfide ultrathin nanosheets as an efficient electrocatalyst for hydrogen evolution.
Molybdenum disulfide (MoS₂) ultrathin nanosheets, as a well-known inorganic two dimensional (2D) material with a graphene-like structure, has attracted tremendous attention due to its unique microscopic and macroscopic properties brought by the confinement of charge and heat transfer upon the basal plane. However, as the prototype Mott-insulator, its relatively low conductivity and carrier conc...
متن کاملSolid State Process for Preparation of Nickel Oxide Nanoparticles: Characterization and Optical Study
In the present work, we report preparation of NiO nanoparticles with well-defined plate morphology by solid-state reaction of NiCl2∙6H2O and the Schiff base ligand N,N′-bis-(3-methoxysalicylidene)benzene-1,4-diamine), as a novel precursor via solid state thermal decomposition method. This method is a simple and environmentally friendly for preparing t...
متن کاملStructure 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...
