摘要
本研究中,具有内在氧空位的Fe OOH亚纳米线被用作一种高性能电催化剂,用于在室温下将硝酸盐转化为NH_(3)。Fe OOH亚纳米线通过水热法制备得到,利用透射电子显微镜、X射线衍射仪和X射线光电子能谱对Fe OOH的形貌结构和物理化学性质进行表征。结果表明,在含有0.1M Na NO_(3)的0.1M磷酸盐缓冲液(PBS)中进行电催化实验时,Fe OOH亚纳米线能够获得2501μg·(h·cm^(2))^(-1)的NH_(3)产量和92%的高法拉第效率(Faradic efficiency,FE),并具有出色的稳定性。
In this study,FeOOH subnanowires with intrinsic oxygen vacancies were used as a high-performance electrocatalyst for the conversion of nitrate to ammonia at room temperature.FeOOH subnanowires were prepared by the hydrothermal method.The morphology,structure and physical and chemical properties of FeOOH were characterized by transmission electron microscopy,X-ray diffractometer and X-ray photoelectron spectroscopy.When electrocatalytic experiments were carried out in 0.1M phosphate buffered solution(PBS)containing 0.1M NaNO_(3),the FeOOH subnanowires achieved an NH3 yield of 2501μg·(h·cm^(2))^(-1) and a high Faradaic efficiency of 92%with excellent stability.
