【摘要】 采用程序升温还原（ＴＰＲ）技术和原位Ｘ射线衍射（ＸＲＤ）方法对含ＣｕＯ催化剂的还原行为和晶相变化进行了详细研究。研究发现，ＣｕＯ在还原过程中经历了ＣＵ２＋→Ｃｕ２Ｏ→ＣＵ０两个阶段，并且在ＣｕＯ中加ＺｎＯ、Ａｌ２Ｏ３后，提高了ＣｕＯ的分散度，降低其还原阻力和表观反应活化能。更多还原

【Abstract】 Temperature-programmed reduction(TPR) and XRD techniques have been used toexamine the reduction behavior and crystalphase changes of the catalysts containingCuO. There exist two stages for CuO in reducing process: Cu2+ → Cu2O → Cu0.When ZnO and/or Al2O3 is added, the dispersion degree of CuO is increased, and reductionimpedance and apparent reaction activation energy are decreased.更多还原
