氘代水處理催化劑
|
| 我在做水處理催化劑的研究,但是現(xiàn)在在做驗證機(jī)理部分,想驗證是否是水在催化劑表面生產(chǎn)羥基的原因,我想將水換成氘代水做對比實驗,看看是不是是水的作用,各位覺得可行嗎?你們對此有沒有好的建議?能不能指教一下??謝謝! |

Catalytic total oxidation of 1, 2-dichloroethane over VOx/CeO2 catalysts: Further insights via isotopic tracer techniquesOriginal Research Article In Press, Accepted Manuscript, Available online 22 October 2015 Qiguang Dai, Li-Li Yin, Shuxing Bai, Wei Wang, Xingyi Wang, Xue-Qing Gong, Guanzhong Lu http://www.sciencedirect.com/sci ... i/S0926337315301983 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. |
