“…Likewise, the discharge capacities of carbon-coated TiO 2 sample are higher than the pristine TiO 2 , and the first and 10th discharge capacities reach about 230 and 209 mAh g −1 , respectively. Furthermore, discharge capacity of carbon innercoated TiO 2 sample is higher than many values previously reported in the literatures [25,14].…”

Carbon innercoated ordered porous TiO 2 were prepared by anodic oxidation of pure titanium sheets, followed by in situ decomposition of glucose in the TiO 2 . Structure, morphology, and electrochemical properties of the composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and a variety of electrochemical testing techniques. Initial discharge capacity and cycling performance of ordered porous TiO 2 were improved dramatically by the inner carbon coating. Migration of Li ions and electrons in the carbon layer was beneficial to suppress the charge transfer resistance of TiO 2 electrode, which resulted in significant improvement in electrochemical performances.

“…As an allotrope of graphite, CNTs are a good anode material for LIBs due to their unique structure (one-dimensional cylindrical tubule of graphite sheet), high conductivity (10 6 S m À1 at 300 K for SWNTs and >10 5 S m À1 for MWNTs) [106], low density, high rigidity (Young's modulus of the order of 1 TPa) [107,108], and high tensile strength (up to 60 GPa) [109]. Reversible capacities of SWNTs fall anywhere from 300 to 600 mAh g À1 [20,[110][111][112][113][114][115][116], which is significantly higher than graphite. Furthermore, mechanical and chemical treatments to the SWNTs can further increase the reversible capacities up to 1,000 mAh g À1 [117][118][119][120].…”

The SWNTs with a carbon content of approximately 3% were synthesized via the disproportionation of CO over a CoMo/SiO 2 catalyst. The three sequential steps, including acid treatment, silica dissolution, and froth flotation, were proposed for the purification of the as-synthesized SWNTs. The pretreatment step for the catalyst removal by acid leaching was optimized at an HCl concentration of 6 M, 50 C, and a sonication time of 3 h, corresponding to the Co and Mo removals of 84% and 44%, respectively. For the silica dissolution, the SWNTs sample after the acid leaching step was treated with a 5 M NaOH solution at 50 C and a sonication time of 3 h, leading to a silica removal of 54%. The froth flotation was employed to separate the SWNTs from the remaining silica using SDBS as an anionic frother. The process performance was maximized at an SDBS concentration of 0.1 Â CMC, an air flow rate of 120 cm 3 /min, and a solution pH of 5, yielding a carbon content of the purified SWNTs of 71%. It was also found that the proposed technique successfully purified the as-synthesized SWNTs sample without damaging its nanostructure.
