摘要/Abstract

摘要：

以钛网作为基底，采用阳极氧化、氨气氮化的方法制备了TiN纳米管，随后电沉积CoSe，制备了CoSe/TiN/Ti同轴纳米管阵列电极。循环伏安结果表明，CoSe/TiN/Ti电极对I₃^-具有高的电催化还原性能，这归因于高催化活性的CoSe和高导电的TiN的协同效应。以CoSe/TiN/Ti电极作为对电极组装染料敏化太阳能电池，电池的能量转换效率高达9.25%，比传统Pt/FTO对电极组装的电池（8.09%）高1%。这一结果为非Pt对电极纳米结构的设计提供了一个很好的思路。

Abstract:

Coaxial CoSe/TiN nanotube arrays have been designed for high performance counter electrodes of dye-sensitized solar cells. This hybrid counter electrodewas prepared by electrodepositing CoSe into TiN nanotube arrays, which are prepared by anodization of a Ti mesh substrate and subsequent nitridation using ammonia annealing. The CoSe/TiN counter electrode displayed excellent performance comparable to Pt/FTO counter electrode due to the effectively combined network of both high electrical conductivity and more favorable and efficient interfacial active sites. The energy conversion efficiency of the cell with CoSe/TiN/Ti as counter electrode reached 9.25%, which was superior to 8.09% of the cell with Pt/FTO counter electrode under the same experimental conditions. These results demonstrate that the coaxial composite nanostructureis very promising for the structure-controllable counter electrode (CE) material.
