Thermal Stability and Anisotropic Sublimation of Two-Dimensional Colloidal Bi2Te3 and Bi2Se3 Nanocrystals
The structural and compositional stabilities of two-dimensional (2D) Bi2Te3 and Bi2Se3 nanocrystals, produced by both colloidal synthesis and by liquid phase exfoliation, were studied by in situ transmission electron microscopy (TEM) during annealing at temperatures between 350 and 500 °C. The sublimation process induced by annealing is structurally and chemically anisotropic and takes place th...
متن کاملPreparation of ZnO Nanocrystals with Desired Morphology from Coordination Polymers through a Solid-state Decomposition Route
One-dimensional (1D) coordination polymer, [Zn(4,4´-bpy)(H2O)4](ADC).4H2O (1) (4,4´-bpy = 4,4´-bipyridine and H2ADC = acetylenedicarboxylic acid), and three-dimensional (3D) metal-organic framework (MOF), Zn(ADC)2.(HTEA)2(2) (HTEA = triethylamine) were prepared at room temperature. The compounds were characterized by single-crystal X-ray diffraction and powder X-ray diffraction (PXRD) analyses....
متن کاملThe Ti3AlC2 MAX Phase as an Efficient Catalyst for Oxidative Dehydrogenation of n‐Butane
Dehydrogenation or oxidative dehydrogenation (ODH) of alkanes to produce alkenes directly from natural gas/shale gas is gaining in importance. Ti3 AlC2 , a MAX phase, which hitherto had not been used in catalysis, efficiently catalyzes the ODH of n-butane to butenes and butadiene, which are important intermediates for the synthesis of polymers and other compounds. The catalyst, which combines b...
متن کاملSynthesis and Characterization of Hydroxyapatite Nanocrystals via Chemical Precipitation Technique
In this study, hydroxyapatite (HA) nanocrystals have been synthesized via chemical precipitation technique. Diammonium hydrogen phosphate and calcium nitrate 4-hydrate were used as starting materials and sodium hydroxide solution was used as the agent for pH adjustment. The powder sample was evaluated by techniques such as scanning electron microscope, transmission electron microscope, Fou...
متن کاملAqueous oxidation reaction enabled layer-by-layer corrosion of semiconductor nanoplates into single-crystalline 2D nanocrystals with single layer accuracy and ionic surface capping.
A controllable aqueous oxidation reaction enabled layer-by-layer corrosion has been proposed to prepare high-quality two-dimensional (2D) semiconductor nanocrystals with single layer accuracy and well-retained hexagonal shapes. The appropriate oxidizing agent, such as H2O2, Fe(NO3)3, and HNO3, could not only corrode the layered-crystalline-structured Bi2Te3 nanoplates layer-by-layer to be a sin...
