催化研究中的ESR低温现场检测装置的改进
Improvement of ESR Device For in situ Detection at Low Temperature in Study of Catalysis
Abstract
在开发研制低温现场检测装置的基础上进行了低温检测装置的改进，有效克服了传统指型杜瓦的局限性以及吹气法中循环冷气因结冰而堵塞、不畅的现象.经过催化剂的现场实验后认为该装置是一种简便、实用的催化研究低温现场检测装置. A ESR in situ detection equipment developed previously by the auther has been Further improved so as to better adapt to in situ detection at low temperatures.Limitations of Finger model dewar and stopping up of ice cycle of gas appearance were eFFiciently overcome in blowing gas way.By many experimental operations, it was proved that this is a simple, practical ESR detecting device For in situ study of catalysis at low temperature.
