Easy synthesis of hollow core, bimodal mesoporous shell carbon nanospheres and their application in supercapacitor.
Hollow core, mesoporous shell carbon nanospheres (HCMSs) with large bimodal mesopores (6.4 and 3.1 nm) and high surface area (1704 m(2) g(-1)) have been synthesized by a triconstituent surface co-assembly of monodisperse silica nanospheres method. The resulted HCMS show a high specific capacity of 251 F g(-1) at 50 mV s(-1) in 2 M H(2)SO(4) and long cyclic life.
متن کاملFabrication of bimodal porous silicate with silicalite-1 core/mesoporous shell structures and synthesis of nonspherical carbon and silica nanocases with hollow core/mesoporous shell structures.
In this work, an attempt has been made to modify the shape and nanostructure of core-shell materials, which have been usually generated on the basis of amorphous spherical cores. Novel core-shell silicate particles, each of which consists of a silicalite-1 zeolite crystal core and mesoporous shell (ZCMS), were synthesized for the first time. The ZCMS core-shell particles are unique because they...
متن کاملFabrication of mesoporous core-shell structured titania microspheres with hollow interiors.
Thermally stable mesoporous core-shell structured titania microspheres with well-defined hollow interiors were directly prepared by a novel hydrothermal precipitation of TiCl4 in the presence of urea and ammonium sulfate.
متن کاملTemplate Synthesis of Hierarchical Bi2E3 (E ) S, Se, Te) Core-Shell Microspheres and Their Electrochemical and Photoresponsive Properties
Hierarchical, core-shell structured microspheres of bismuth chalcogenides (Bi2E3, E ) S, Se, Te) have been synthesized by chemical transformation of reactive precursor templates, which involves the formation of intermediate BiOCl mircrospheres and their subsequent hydrothermal transformation into Bi2E3 core-shell microspheres. The uniform precursor microspheres consisting of BiOCl nanoplates we...
متن کاملSynthesis and Electrochemical Study of Nano Graphitic Mesoporous Carbon
In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and its structural properties were characterized by nitrogen physisorption isotherms, transmission electron microscopy and Raman spectroscopy. According to BET and BJH methods, the specific surface area (SBET) and the average pore diameter of GMC are estimated to be 720 m2/g and 3.4 nm, respectively....
