本文介绍了胺模板法制备的孔内含有聚噻吩纳米线的介孔二氧化钛的合成和表征。这些材料被设计来改善钙的电子传导性。1000 m2/g介观结构，以利用孔内的氧化还原位点。的合成复合材料，包括这些材料的电化学评估的深入表征，并与原始的介孔氧化钛。结果表明，成功的合成导电纳米线的孔内的介孔钛氧化物，通过利用气相扩散和原位聚合，同时保留介观结构的钛氧化物主机。介孔氧化钛在0.2 mA cm-2的电流密度下产生301 mAh/g的峰值容量。聚噻吩纳米线提高了材料的导电性，但容量略有下降。
This paper describes the synthesis and characterisation of amine-templated mesoporous titanium oxide with polythiophene nanowires in the pores. These materials were designed to improve the electron conductivity of the ca. 1000 m2/g mesostructure in order to exploit the redox sites within the pores. An in depth characterisation of the synthesised composites including an electrochemical assessment of these materials is presented, and compared to the pristine mesoporous titanium oxide. The results demonstrate successful synthesis of conducting nanowires within the pores of the mesoporous titanium oxides by utilising vapour diffusion and subsequentin situpolymerisation, whilst retaining the mesostructure of the titanium oxide host. The mesoporous titanium oxide produced a peak capacity of 301 mAh/g at current densities of 0.2 mA cm−2. The polythiophene nanowires improve the conductivity of the material with a slight drop in capacity.
