| 英文摘要 | Nowadays, it is necessary to discover the interactions of O-3 with metal oxides in order to synthesize active O-3 degradation catalysts. Herein, ZnO is adopted as a model and the crystal defects are tuned by annealing in H-2 and O-2, and by doping with Ga and Li. The H-2 annealed ZnO behaves far higher activity towards 20 ppm O-3 than those as-obtained and O-2 annealed ones, and the activity can be further improved by doping with Ga donors and Li acceptors. The mechanism investigation shows that the oxygen vacancy induced by H-2 annealing favors the activity while the oxygen interstitials depress it, implying that there existed electron transfer between crystal defects, O-3 and the intermediate species. Furthermore, the deactivation of catalyst is attributed to the filling out of the oxygen vacancy. All these results provide fundamental understanding for further improvement of O-3 degradation catalysts. |
