| description | The porous TiO<sub>2</sub> powders were prepared by sol-gel method using titanium tetrachloride as titanium source, P123 as template agent and cyanamide as stabilizer agent, respectively. The porous TiN powders were synthesized <i>via</i> reduction and nitridation of the porous TiO<sub>2</sub> powders at 900℃ in NH<sub>3</sub>. The phase composition and microstructure of the porous TiN powders were characterized by the XRD, SEM, BET, TEM and SAXD. The electrochemistry performance of the porous TiN powders was evaluated through the cyclic voltammetry, AC impedance and constant current charge-discharge techniques. The results show that the porous powders have approximate spherical particles with cubic TiN phase. Compared to the porous TiN powders without P123 adding, the mesopores with pore diameter range of 10-50nm increased in the porous TiN powders with P123 adding. There are also some pores with size range of 2-3nm. Meanwhile the porous TiN powders with P123 adding exhibit more ordered mesopores. This porous structure can improve the electrochemistry performance of the TiN powders. As a result, for the porous TiN powders without P123 adding, the specific capacitance is 81F·g<sup>-1</sup>. The internal resistance <i>R</i><sub>1</sub> is 1.1Ω, and the ion diffusion impedance <i>W</i><sub>1</sub> is 2.5Ω. For the porous TiN powders with P123 adding, the specific capacitance is increased to 95F·g<sup>-1</sup>, the <i>R</i><sub>1</sub> and <i>W</i><sub>1</sub> value are decreased to 0.9Ω and 0.06Ω, respectively. |
