Studies on Syntheses of FeOOH and P_20_4/n-heptane System Saponified by NH_3·H_2O

本文利用氨水皂化后P204-正庚烷体系,以不同的方式加入氢氧化钠,在水热条件下制备出了氧化氢氧化铁纳米棒和立方状纳米氧化铁,为纳米氧化氢氧化铁和氧化铁的制备提供了新途径.氧化氢氧化铁纳米棒宽约15～27 nm,长约100～250 nm,立方状氧化铁粒径在80 nm左右.并对反应条件对产物的影响和生成机理进行了讨论.

FeOOH nanorods with width of 15~27 nm and length of 100~250 nm and 稨2O. The method for NaOH addition had a significant effect on the phase and morphology of the final product. Some of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The structure of organic phase was characterized by FT-IR. The reaction conditions and the mechanism were also studied.
