采用水热法在掺氟氧化锡玻璃(FTO)衬底上制备了一种用于光电化学(PEC)电池的新型Fe2O3/金红石型纳米棒(NR)阵列。Fe2O3被认为是一种廉价、环保的半导体增感剂，可以使TiO2对可见光做出响应。利用这种光阳极，详细研究了基于一维(1D)Fe2O3/TiO2异质结的PEC电池在模拟太阳光下的光电转化和水分解特性。同时，通过调节Fe_2O_3的掺杂量，实现了光伏性能的优化。Fe_2O_3/TiO_2太阳电池的开路电压和短路电流分别可达0.435毫安和1.840毫安/厘米~2。此外，在平带电势结果的基础上，对光电效应进行了初步的理论分析。
We reported a novel Fe2O3/rutile TiO2nanorod (NR) arrays with the heterogeneous structure for photoelectrochemical (PEC) cells, which were fabricated on fluorine-doped tin oxide glass (FTO) substrates that serve as model architecture via a hydrothermal method. Fe2O3was revealed as an inexpensive and eco-friendly semiconductor sensitizer to make TiO2respond to visible light. By using this photoanode, the photoelectric conversion and water splitting properties of PEC cells based on the one-dimensional (1D) Fe2O3/TiO2heterostructures were investigated in detail under simulated sunlight. Meanwhile, the optimization of photovoltaic performance was also achieved by regulating the amount of Fe2O3. The open circuit voltage and short circuit current of the Fe2O3/TiO2solar cell can reach 0.435 V and 1.840 mA/cm2, respectively. In addition, theoretical analysis of the photoelectric effect is preliminarily explored on the basis of the flat band potential results.
