AbstractA three-step method was used for the synthesis of mesoporous carbon sphere (MCS) material: firstly, silica (SiO2) nanoparticles were synthesized by the modified Stöber procedure; secondly, tetraethyl orthosilicate (TEOS) and cetyltrimethylammonium chloride (CTAC) were grafted onto SiO2 core nanoparticles to prepare SiO2@SiO2-CTAC hard templates; lastly, MCS material was fabricated by carbonizing and selective leaching SiO2/resorcinol-formaldehyde (RF) composites. The influence of the mass ratio of R-F/silica on the structure, morphology and crystal form was studied. The results indicate that the MCS materials have a uniform morphology. The increase of the mass ratio of R-F/silica can increase the specific surface area and pore volume. The three-step method provides a cost-effective procedure for the fabrication of MCS materials with uniform morphology.

Mesoporous C@FexSy composite as a negative electrode for supercapacitors was synthesized via a one-step hydrothermal treatment followed by an electrodeposition process and its electrochemical properties were studied. Compared with bare carbon sphere, the electrochemical performance of C@FexSy composite was significantly improved, with a high specific capacitance (267.45 F/g), good rate performance (201.08 F/g at 2.5 A/g), and superior cycling stability (almost no capacitance degradation after 1000 cycles). The results show that the obtained C@FexSy composite is a promising negative electrode material for supercapacitors
