Metal@Silica yolk-shell nanostructures as versatile bifunctional nanocatalysts

Yolk-Shell Nanostructures: Design, Synthesis, and Biomedical Applications.

Yolk-shell nanostructures (YSNs) composed of a core within a hollow cavity surrounded by a porous outer shell have received tremendous research interest owing to their unique structural features, fascinating physicochemical properties, and widespread potential applications. Here, a comprehensive overview of the design, synthesis, and biomedical applications of YSNs is presented. The synthetic s...

Diffusion through the shells of yolk-shell and core-shell nanostructures in the liquid phase.

Recent advances in synthetic materials sciences such as the incorporation of self-assembly, sol–gel, and layer-by-layer deposition chemistry have afforded the development of many interesting and potentially useful nanostructures. Among those, nanoarchitectures in which a core nanoparticle, often a transition metal, is encapsulated by an outer layer of a second material, typically a porous oxide...

Laser-induced transformation of supramolecular complexes: approach to controlled formation of hybrid multi-yolk-shell Au-Ag@a-C:H nanostructures

In the present work an efficient approach of the controlled formation of hybrid Au-Ag-C nanostructures based on laser-induced transformation of organometallic supramolecular cluster compound is suggested. Herein the one-step process of the laser-induced synthesis of hybrid multi-yolk-shell Au-Ag@a-C:H nanoparticles which are bimetallic gold-silver subnanoclusters dispersed in nanospheres of amo...

Bimetallic Janus nanostructures via programmed shell growth.

We report the synthesis of compositionally asymmetric, core-Janus shell plasmonic nanostructures comprised of Au and Ag. Kinetic control was employed to achieve asymmetric shell growth on Au nanoparticles acting as cores. Subsequent differential surface functionalization of these nanostructures enabled programmed shell growth resulting in core-Janus shell nanostructures. UV/vis extinction spect...
