Engineering nonspherical hollow structures with complex interiors by template-engaged redox etching
Despite the significant advancement in making hollow structures, one unsolved challenge in the field is how to engineer hollow structures with specific shapes, tunable compositions, and desirable interior structures. In ...
Fabrication of core−shell structure of M@C (M=Se, Au, Ag2Se) and transformation to yolk−shell structure by electron beam irradiation or vacuum annealing
Selenium @ carbon core−shell spheres have been synthesized via a simple one-step hydrothermal carbonization process using sucrose and sodium selenite as precursors. Metal selenide or noble metal, e.g. Ag2Se or Au, can be ...
Constructing hierarchical spheres from large ultrathin anatase TiO2 nanosheets with nearly 100% exposed (001) facets for fast reversible lithium storage
Synthesis of nanocrystals with exposed high-energy facets is a well-known challenge in many fields of science and technology. The higher reactivity of these facets simultaneously makes them desirable catalysts for sluggish ...
Controlled synthesis of Sb nanostructures and their conversion to CoSb3 nanoparticle chains for li-ion battery electrodes
Nanostructured Sb was prepared through a simple polyol process. Either Sb nanoparticles (Sb NP) or nanowires (Sb NW) were obtained by adjusting the concentration of surfactant. Electrochemical analyses revealed that the ...
