摘要

8%CuO_x/ZnO_y and 8%Co,4%CuO_x/ZnO_y are shown by residual gas analysis (RGA) and differential scanning calorimetry (DSC) to be active in sustained N_2O decomposition above 773K. Transient experiments on 8%CuO_x/ZnO_y at 473K suggest that UV irradiation enhanced this reaction (and the subsequent desorption of O_2) and moreover this activity was retained even after the irradiation of the catalyst is terminated. This may be important in the propulsion of small satellites with a low power requirement, but new materials technology will be required.
