Abstract: Photoelectrocatalytic technology can provide an energy conservation and environmental protection way for environmental governance and chemical production. High efficient photoanodes materials are one of the challenges in the practical application of photoelectrocatalytic technique, therefore, high performance photoanode materials have been designed and developed for enhancing the application efficiency of photoelectrocatalytic technique. Fe2O3 has become a hot spot in the field of photocatalysis because of its narrow band gap, high stability and low price. In order to develop the high performance Fe2O3 photoanodes materials, many studies focused on the energy band position, conductivity and photogenerated the hole diffusion length. This review summarized the preparation techniques (hydrothermal method, spray pyrolysis, chemical vapor deposition, atomic layer deposition, etc), modification methods (“junction” construction, doping, morphological control, ect) and modified hydrogen production of the Fe2O3 photoanodes materials, the challenges and opportunities in this promising research area were proposed.

摘要： 光电催化技术为环境治理和化工生产提供了一条节能、环保的路径。高活性光阳极材料是光电催化技术实际应用的瓶颈问题之一，因此为提高光电催化技术实际应用效率，亟待开发高效的光阳极材料。Fe2O3由于具有禁带宽度窄、稳定性高、价廉等优点成为光电催化研究的热点，且其在光电催化领域展现出良好的应用前景。为获得高效的Fe2O3光电催化剂，研究者针对Fe2O3自身能带位置、导电性差、空穴传输距离短等缺点进行了调控。对近年来在提高Fe2O3催化剂的光电催化性能所采用的制备技术（如水热法、喷雾热分解法、化学气相沉积法、原子层沉积法等）、改性方法（如“结”构建、掺杂、形貌调控等）及其改性后的产氢量进行了概述，并对Fe2O3光电催化剂的发展前景进行了展望。
