| 中文摘要: |
| Spin trapping technique was employed to study the mechanism of photocatalyticdehydrogenation of alcohol during in situ irradiation of Rh_2O_3/CdS powder which is sus-pended in aqueous aicohol solution.Evidence for production of ·OH radical is presentedand the rate of·OH radical formation corresponds to the rate of H_2 evolution.On the ba-sis of the above results,it is suggested that water cleavage is an intermediate step in this reac-tion. |
