Abstract:

Mesoporous TiO₂ whisker prepared by sintering has high crystallinity, its pore size is controllable, and the cost is low, so it can be mass-produced.If the material is used in electrochemical capacitorelectrode, the cost of the capacitor will be cut down.In this paper, mesoporous TiO2 whisker with pore size around 10 nm and TiO2/RuO2 composite material were prepared to make electrodes.The results of cyclic voltammograms showed that the material had typical electrochemical capacitor property even in the neutral solution of 0.1 mol·L^-1 Na2SO4.The capacitor property was within a wide scan range.When the mesoporous TiO ₂ whisker was loaded with RuO ₂, the performance was excellent, and its capacitance was up to 940.4 F·g^-1 (divided by the mass of RuO ₂), so it is feasible to use this material as mass-produced electrode material.
