The invention provides a ferrous oxalate nanowire and a preparation method thereof, and belongs to the technical field of material synthesis. N, N-diethyl acetamide and polyvinyl alcohol are adopted as a composite surfactant, and in the nucleation process of ferrous oxalate crystals, polyvinyl alcohol serves as a nucleation agent to play a template effect; in the ferrous oxalate crystal growth process, N, N-diethyl acetamide is adsorbed on the crystal face of ferrous oxalate to inhibit crystal growth, polyvinyl alcohol and N, N-diethyl acetamide generate a coupling effect, the growth direction and the growth rate of ferrous oxalate are jointly influenced from the angles of crystal nucleation and crystal growth, then the ferrous oxalate nanowire is obtained, and the diameter of the ferrous oxalate nanowire is 15-100 nm; and the method is simple and feasible. 本发明提供了一种草酸亚铁纳米线及其制备方法，属于材料合成技术领域。本发明采用N,N-二乙基乙酰胺和聚乙烯醇作为复合表面活性剂，在草酸亚铁晶体形核过程中，聚乙烯醇作为形核剂，发挥"模板"效应；在草酸亚铁晶体生长过程中，N,N-二乙基乙酰胺吸附在草酸亚铁的晶面，抑制晶体生长，聚乙烯醇和N,N-二乙基乙酰胺发生耦
