[求助] 氘代水处理催化剂

我在做水处理催化剂的研究,但是现在在做验证机理部分,想验证是否是水在催化剂表面生产羟基的原因,我想将水换成氘代水做对比实验,看看是不是是水的作用,各位觉得可行吗?你们对此有没有好的建议?能不能指教一下??谢谢!

2.6.2. H/D exchange of surface hydroxyl groups

H/D exchange was accomplished by passing an 20%O2/Ar feed (30 ml/min) through a water saturator at 25 °C. This feed was then contacted with catalyst (about 50 mg) and placed in an in situ IR spectroscopy at different temperature. The exchange process was followed with IR spectroscopy to monitor the degree of exchange [17]. After H/D exchange of surface hydroxyl groups was completed, the oxidation of DCE (20%O2/Ar stream containing 1000 ppm DCE) was recorded for different time at 200 and 300 °C.
