本文利用电化学沉积法成功制备出铂纳米粒子修饰的取向碳纳米管纤维,并对铂含量进行了有效调控.铂纳米粒子均匀沉积于取向碳纳米管纤维表面,与没有取向纳米结构的其他纤维材料(如碳纤维)相比,更有效的提高了对I3-/I-氧化还原反应的催化活性.基于铂修饰的取向碳纳米管纤维作为对电极构建的纤维状染料敏化太阳能电池获得了高达8.10%的能量转换效率,远高于基于取向碳纳米管纤维及铂修饰的碳纤维获得的4.91%和5.50%的能量转换效率.

In this paper, platinum nanoparticles modified carbon nanotube fibers were successfully prepared by electrochemical deposition method, and the platinum content was effectively regulated.The platinum nanoparticles were uniformly deposited on the surface of oriented carbon nanotube fibers, and other fibers with no oriented nanostructures (Such as carbon fiber), the catalytic activity of I3- / I- redox reaction is more effectively improved.Water-based dye-sensitized solar cells based on platinum-modified oriented carbon nanotubes (MWCNTs) The energy conversion efficiency of 8.10% is much higher than the 4.91% and 5.50% energy conversion efficiencies obtained from oriented carbon nanotube fibers and platinum-modified carbon fibers.
