Abstract:

The ordered mesoporous TiN powder was synthesized by reduction-nitridation method based on the nonhydrolytic sol-gel process using titanium tetrachloride as the raw material, P123 as the structure-directing agent and cyanamide as the stabilizer. The structural information of the composite powder was characterized by wide-angle/small-angle X-ray diffraction, scanning electronic microscopy, N2 adsorption-desorption analysis, and the electrochemical properties were characterized by cyclic voltammetry(CV) and galvanostatic charge-discharge(GCD) measurements. The results show that the synthesized TiN powder was highly pure cubic TiN phase and had ordered mesoporous structure, its specific surface area was 97 m2/g. The CV curves at different scan rates look like the rectangle. The specific capacitance was 233 F/g at current density of 50 mA/g, and remained 90% even after 2000 cycles. When the power density was 0.1 kW/kg, the energy density was as high as 65 W·h/kg.
