铁掺杂的钨酸钴纳米棒的制备及电催化性能研究

摘要

以六水合氯化钴、二水合钨酸钠、硫酸亚铁为原料,采用溶剂热法制备出一种铁离子掺杂的钨酸钴纳米棒.该电催化剂在碱性条件下表现出良好的电催化产氧活性,在1.89 V(vs RHE)时,其电流密度是未掺杂的钨酸钴纳米棒的5倍.%Used CoCl2·6H2O, Na2WO4·2H2O, FeSO4as raw materials, iron-doped CoWO4nanorods were synthesized by a facile solvothermal method. Iron-doped CoWO4nanorods showed highly active in alkaline oxygen evolving reaction for water splitting, which current density was 5 times higher than that of the CoWO4nanorods at 1.89V (vs RHE).
