摘要: 为了降低存在于污水中的重金属离子对自然界以及人体的危害，选用铜铁矿材料CuFeO2作为催化剂光催化降解水溶液中的六价铬。使用水热法，通过改变加入的铜盐与铁盐间摩尔比，获得最佳比例的CuFeO2 (2H相)，并对其微观结构和表面形貌进行了表征。同时制备了Ni2+浓度为1%~2%的掺杂样品，其中2% Ni-CuFeO2可在80分钟内完全降解Cr (VI)。
Abstract: In order to reduce the harm of heavy metal ions in sewage to nature and human body, CuFeO2 was selected as the catalyst for photocatalytic degradation of hexavalent chromium in aqueous solution. The optimal CuFeO2 (2H phase) was obtained by changing the molar ratio of copper salt to iron salt by hydrothermal method, and its microstructure and surface morphology were characterized. At the same time, the doped samples with Ni2+ concentration of 1%~2% were prepared, in which 2% Ni-CufeO2 could completely degrade Cr (VI) within 80 minutes.
