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.
