以δ-FeOOH为晶种由铁低温液相制备纳米氧化铁红
Preparation of nano-sized iron oxide red using δ-FeOOH as seed and iron as raw material in liquid phase at low temperature
摘要
Abstract
Uniform pseudocube nano-iron oxide red (hematite) particles was prepared in the liquid phase by using δ-FeOOH as seed and iron as raw material at low temperature. The effects of such factors as initial pH of reaction, concentration of catalyst, reaction time on the preparation of these hematite particles were investigated. The product was characterized by XRD, IR, FESEM. The results showed that pure pseudocube hematite particles could be prepared under the experimental conditions of solution initial pH 7, β=0. 09 (β=[Fe2+]/[S-FeOOH]) , air oxidation temperature and time of 100°C and 48 h respectively. The product crystallized integrally with particle diameter 90-100 nm, and its color was brightly red. This is a new method to prepare high-purity nano-iron oxide red with the characteristics of simple operation, non-pollution and low cost.关键词
