Graphite Nanocomposites

In this study, CoOOH/Co(OH)2 and CoOOH/Co(OH)2/graphite nanocomposites were obtained using a one-step microwave method. The morphologies of nanocomposites changed intensively by adding trace graphite, thereby affecting the electrochemical properties. The optimum capacitance of the electrode material can reach 402[Formula: see text]F[Formula: see text]g[Formula: see text] at 2[Formula: see text]A[Formula: see text]g[Formula: see text] and could be increased by 172% (692[Formula: see text]F[Formula: see text]g[Formula: see text] until 2200 cycles when the graphite content is 10[Formula: see text]mg. An excellent cycling stability of 86.2% capacitance retention of the highest value was attained after 10,000 cycles, which is higher than those of the CoOOH/Co(OH)2 electrode. The proposed provides a simple means to improve the electrochemical properties by changing the morphology of electrode material in supercapacitors.

Yellow colored anatase Fe/N co-doped TiO2powders have been successfully synthesized by one step hydrothermal method at a lower temperature. The grain size was about 10 nm and the specific surface area of the powders ranged from 160 to 166 m2/g. The light absorption of Fe/N co-doped TiO2powders was enhanced in the visible light region of 400~500 nm and a new absorption peak at about 470 nm appeared when the Fe/Ti ratio exceeded 0.5%. The visible light photoactivity of Fe/N co-doped TiO2powders has been greatly improved than that of un-doped TiO2powders under visible light irradiation.
