摘要
纳米阵列结构由于其优异的物理、化学特性而得到高度关注和深入研究。复合半导体纳米阵列由于其能实现光吸收深度和光生载流子传输距离的解耦合而在太阳能电池及光电化学分解水方面发挥着越来越重要的作用。近年来,我们课题组利用廉价易得的常见半导体材料制备了一系列复合半导体纳米阵列结构,并将这些结构用作光电化学分解水的光阳极材料。我们已经实现的复合半导体纳米阵列包括:CdS/g-C_3N_4纳米棒阵列、TiO_2/g-C_3N_4/CoP i纳米棒阵列、Fe_2O_3/WO_3纳米棒阵列,Fe_2O_3/TiO_2纳米棒阵列以及WO_3/g-C_3N_4纳米片阵列。研究结果显示这些复合纳米阵列结构在光电性能及光电稳定性方面都有优异的表现。
Nano arrays based structure has been investigated intensely due to its unique physical and chemical properties, recently. Composite nano arrays composed of different kinds of semiconductors play important role in the field of solar cell and photoelectrochemical(PEC) water splitting, because we can decouple length scales of the light absorption and charge diffusion and offer sufficient surface area for the photogenerated electrons or holes to diffuse into electrolyte using nano arrays as photo electrode. In the past two years, a serious of composite nano arrays were developed in our group, including CdS /g-C_3N_4, TiO_2/g-C_3N_4/CoP i, Fe_2O_3/WO_3 nanorod arrays and WO_3/g-C_3N_4 nano sheet arrays. Our results show that these nano arrays exhibited enhanced activity for PEC water splitting and prolonged stability against light corrosion.
