Nanosized Re2O7 Powders: Preparation by Extraction Method and Photocatalytic Behaviour |
|
摘要: 本工作从N235-正庚烷萃取体系中,以饱和萃取法制得前体物和纳米粉体Re2O7,平均粒径30 nm。以此纳米粉为光催化剂,研究了光降解甲基橙染料的最佳条件,并在相同条件下,与非纳米Re2O7及工业常用的纳米TiO2进行比较,光降解甲基橙能力大小为:纳米Re2O7 > 锐钛矿型纳米TiO2 > 非纳米Re2O7。 |

Abstract: The precursor and nanosized powder Re2O7 with an average grain size of 30 nm were prepared in the extraction system of N235-n-heptane with the saturated extraction method. The optimum conditions for degrading Methyl Orange dyestuff with this nanosized powder as photocatalyst was studied. The catalytic performance of the title material was compared with non-nanosized Re2O7 and industrial TiO2. The order of activity is nanosized Re2O7 > anatase nanosized TiO2 > non-nanosized Re2O7. |
