Iron alkoxide complex Fe(OEt)2(acac) was directly synthesized by electrochemical dissolution of iron for 8 h at 50 ℃ in a cell without separating the cathode and anode spaces.The product was characterized by FTIR

Raman spectra and NMR.The xerogel was prepared by a direct sol-gel and dryness of the electrolyte solution

which was heated at 450 ℃ for 2 h to obtain the nano-Fe2O3 powder.FT-IR

XRD

and TEM were used to investigate the structure of nano-Fe2O3.The experiments show the iron complex is Fe(OEt)2(acac)

which contains acac group and can prevent hydrolysis and calcinations of the precursor from gathering.The xerogel of 10 nm and high purity nano-Fe2O3 of 20~30 nm were thus obtained.
