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 ...
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 ...
Template-assisted formation of rattle-type V2O5 hollow microspheres with enhanced lithium storage properties
In this work, rattle-type ball-in-ball V2O5 hollow microspheres are controllably synthesized with the assistance of carbon colloidal spheres as hard templates. Carbon spheres@vanadium-precursor (CS@V) core–shell composite ...
