Three times SCR test

To ensure data reliability of NOx conversion, N2 selectivity and N2O concentration during the SCR reaction over CeNbOx/SSZ-13, CeNbOx/SSZ-13-KNO3, CeNbOx/SSZ-13-KCl and CeNbOx/SSZ-13-KOH catalysts, all activity data in the revised manuscript are derived from at least three independent replicate tests, and error bars in reflect the reproducibility of results.

为保障CeNbOx/SSZ-13、CeNbOx/SSZ-13-KNO3、CeNbOx/SSZ-13-KCl及CeNbOx/SSZ-13-KOH催化剂在选择性催化还原（SCR）反应中氮氧化物（NOx）转化率、氮气选择性与一氧化二氮（N2O）浓度相关数据的可靠性，本修订稿件中的所有活性数据均来自至少三次独立重复测试，误差棒可反映实验结果的可重复性。
