还原态铁／活性炭催化剂的聚苯乙烯包膜研究

A STUDY OF THE FILM COATING OF POLYSTYRENE OVER THE REDUCTIVE STATE OF IRON/ACTIVE CARBON CATALYST

用聚苯乙烯对还原后极易氧化的Ｆｅ／Ａｃ（铁／活性炭）催化剂作包膜保护，其方法简易。包膜后的实验结果：在穆斯堡尔谱（ＭＢＳ）测定中，样品中超顺磁体小颗粒的Ｆｅ２Ｏ３含量增高５％；但在Ｘ射线衍射（ＸＲＤ）及红外光谱（ＩＲ）的测定中，包膜后的测定结果理想，表明还原样品可用聚苯乙烯包膜后。

A film of polystyrene is used to cover the reduced iron/active carbon catalyst which is easy to reoxidize, and this method is quite simple. The experimental results of the film coating sample show that the super paramagnetic particles of Fe 2O 3 are increased by a factor of 0.05 in the measurement of Mossbauer spectroscopy (MBS), but, the X ray diffraction (XRD) and Infrared spectrum (IR) measurements are very satisfactory. This indicates that the film coating of polystyrene can be used to obtain the correct results of XRD and IR of the reductive sample when the experimental measurements for the in situ conditions cant.
