摘要

二氧化钛(TiO2)纳米线(管)是一种具有较大比表面积的一维纳米材料,具有优秀的可逆容量、高化学稳定性和良好的赝电容特性,能降低光生电子-空穴对的复合率,并作为电子定向移动的通道。石墨烯是一种碳原子以sp2杂化形成的只有一个原子厚度的二维材料,具有超高的物理和力学性能。将石墨烯与TiO2纳米线(管)复合,可以同时发挥这两种材料的性能优势,在锂离子电池、超级电容器和光催化等领域应用广泛。综述了TiO2纳米线(管)-石墨烯的制备方法及其应用现状,并对其应用前景进行了展望。

Abstract

TiO2 nanowire (tube) is one-dimensional nanomaterial with large specific surface area.It has excellent reversible capacity,high chemical stability and good pseudocapacitive characteristics.At the same time,it can reduce the recombination rate of photogenerated electron-hole pairs and it can be used as the channel for electron directional movement.Graphene is a two dimensional material formed by the hybridization of sp2 atoms with only one atom thickness.It has high physical and mechanical properties.TiO2 nanowire (tube)-graphene was prepared by combining graphene with TiO2 nanowire (tube),which can take the performance advantage of two materials,and widely used in lithium ion batteries,supercapacitors and photocatalysis.The preparation methods and the applications of TiO2 nanowire-graphene were reviewed.
