Synthesis of porous hollow silica nanostructures using hydroxyapatite nanoparticle templates.
Porous hollow spherical and rod-like silica nanoparticles were obtained via a surfactant templating method adopting hydroxyapatite (HAp) nanoparticles as an etchable core material.
متن کاملHeterogeneous ZnS hollow urchin-like hierarchical nanostructures and their structure-enhanced photocatalytic properties.
Hexagonal wurtzite ZnS nanowires radially arrayed on cubic zinc-blende ZnS hollow spheres have been successfully achieved for the first time, and such novel heterogeneous ZnS hollow urchin-like hierarchical nanostructures show greatly enhanced photocatalytic properties due to their two-phase enhanced light-harvesting and high surface-to-volume ratio.
متن کاملEffect of Ag Templates on the Formation of Au-Ag Hollow/Core-Shell Nanostructures
Au-Ag alloy nanostructures with various shapes were synthesized using a successive reduction method in this study. By means of galvanic replacement, twined Ag nanoparticles (NPs) and single-crystalline Ag nanowires (NWs) were adopted as templates, respectively, and alloyed with the same amount of Au(+) ions. High angle annular dark field-scanning TEM (HAADF-STEM) images observed from different ...
متن کاملOptical excitations in stoichiometric uncapped ZnS nanostructures.
We calculate the optical absorption spectra of low-energy uncapped zinc sulfide nanostructures found by global optimisation (basin-hopping/simulated annealing) using time-dependent density functional theory (TD-DFT) and compare the results with experimental spectra. We predict that for all nanostructures studied the lowest excited state found by TD-DFT corresponds to an exciton with an exciton ...
متن کاملGrowth of anisotropic one-dimensional ZnS nanostructures{
Anisotropic growth in nanomaterials can lead to many interesting growth morphologies. This is especially true when the crystal structure contains anisotropy not only due to different surface plane energies but also due to surface polarity and/or chemical activity. Such is the case with wurtzite ZnS. This feature article covers the ZnS one-dimensional nanostructures that have been synthesized by...
