Since FeO is a promising photoanode material for water splitting, it has attracted much attention, while other phases of ferric oxide are ignored. Here, β-FeO was used as a photoanode material for solar water splitting. The crystal structure and phase of β-FeO were characterized by using X-ray diffraction, X-ray photoelectron spectroscopy, Raman scattering, Mössbauer spectra and a superconducting quantum interference device. The photocurrent density of the β-FeO photoanode at 1.6 V was 0.12 mA·cm under the illumination of simulated sunlight (AM1.5G, 100 mW cm).
由于FeO是一种很有前景的用于水分解的光阳极材料，它已引起了广泛关注，而氧化铁的其他相则被忽视。在此，β-FeO被用作太阳能水分解的光阳极材料。通过X射线衍射、X射线光电子能谱、拉曼散射、穆斯堡尔谱和超导量子干涉装置对β-FeO的晶体结构和相进行了表征。在模拟太阳光（AM1.5G，100 mW/cm²）照射下，β-FeO光阳极在1.6 V时的光电流密度为0.12 mA·cm² 。
