摘要：
By adding CuO into heated Fe(NO3)(3) aqueous solution, a precipitation reaction takes place to form nanosized iron oxide. The product obtained were characterized by transmission electron microscopy(TEM), vibrating sample magnetized(VSM), X-ray diffraction(XRD), energy disperse X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy(XPS). The experimental results showed that the product is weakly magnetic nanoclusters based on smaller ferrihydrite Fe5O7(OH)center dot 4H(2)O nanocrystallites. The nanoclusters are of about 40 nm size and absorbed by Fe(NO3)(3). The experimental results are attributed to the Fe(NO3)(3) hydrolysis reaction being enhanced by CuO as hydrolyte. A new route is proposed for the preparation of nanosized oxide using hydrolysis enhanced.
