水热合成法制备氧化铁微纳米棒及其光催化性能

Photocatalytic Property of Fe2O3 Micro/nanorods by Hydrothermal Synthesis

利用Fe2(SO4)3·9H2O作为铁源,十六烷基三甲基溴化铵(CTAB)作为分散剂,通过水热合成法制得Fe2O3微纳米棒。通过XRD、SEM表征和分析Fe2O3的形貌。探究在紫外光照射下,微纳米Fe2O3光催化降解亚甲基蓝的性能。实验结果表明,紫外光照射180 min后,微纳米Fe2O3对亚甲基蓝的光催化降解率可高达94. 68%。

The Fe2O3 micro/nanorods were synthesized using Fe2(SO4)3·9H2O as iron source and hexadecyl trimethyl ammonium bromide( CTAB) as dispersant by hydrothermal synthesis. XRD and SEM were used to characterize and analyze the morphology of Fe2O3. The degradation ability of Fe2O3 micro/nanorods to methylene blue( MB) solution were investigated under UV light. The results showed that after 180 minutes under UV light irradiation,the degradation rate of methylene blue was 94. 68%.
