英文摘要	It is generally accepted that CeTiOx catalyst owns outstanding catalytic activity for ammonia-selective catalytic reduction (NH3-SCR), but the tolerance to alkali metals is still dissatisfactory. Thus, it is of great importance to further elevate the catalytic activity and resistance to alkali metals of CeTiOx catalyst. In our work, a series of CeTiOx, CuO/CeTiOx, K-CeTiOx and K-CuO/CeTiOx catalysts were prepared to comprehensively analyze the influence of CuO modification on the physicochemical features, catalytic activity and anti-K ability of CeTiOx catalyst. The results manifest that CuO modification effectively enhances low-temperature catalytic activity and anti-K poisoning ability of CeTiOx catalyst by protecting the reduction ability and the surface acidity as well as weakening the adsorption strength of NOx.
