The SCR activities of MoO3-CeO2 catalysts are enhanced by both Lewis and Brønsted acidities provided by surface cerium atoms and amorphous MoO3 structures, respectively, but are suppressed by stable adsorbed nitrate or nitrite species on the defect sites of CeO2.
MoO3-CeO2 催化剂的 SCR 活性分别受表面铈原子提供的路易斯酸和 Brønsted 酸以及无定形 MoO3 结构的增强，但受 CeO2 缺陷位上稳定吸附的硝酸盐或亚硝酸盐物种的抑制。
