Here, we report the fabrication of self-organized titania (TiO(2)) nanotube array supercapacitor electrodes through controlled phase transformation of TiO(2), with aerial capacitances as high as 2.6 mF cm(-2), which far exceeds the values so far reported in the literature. The role of phase transformation in the electrochemical charge-discharge behaviour of nanocrystalline TiO(2) nanotubes is investigated and discussed in detail. The ease of synthesis and the exceptional electrochemical properties make these nanotube arrays an alternative candidate for use in energy storage devices.
在这里，我们通过 TiO(2) 的控制相转变来报告自组织的二氧化钛（TiO(2)）纳米管阵列超级电容器电极的制造，具有高达 2.6 mF cm(-2) 的比空气电容，远远超过了目前文献中报道的值。我们详细研究和讨论了相转变在纳米晶 TiO(2) 纳米管的电化学充放电行为中的作用。这种合成的简便性和优异的电化学性能使得这些纳米管阵列成为储能装置的一种替代候选材料。
