本文介绍了同步加速器在O-2/He和标准NH3-SCR反应条件下激活两种Cu- ssz -13催化剂时的原位时间分辨PXRD研究结果，以深入了解Cu离子的行为。所得结果表明，deNO(x)活性与沸石6r的占位密切相关。
Here we present the results of a synchrotron-based in situ, time-resolved PXRD study during activation of two Cu-SSZ-13 catalysts under O-2/He and one during standard NH3-SCR reaction conditions to obtain insight into the behaviour of Cu ions. The results obtained indicate that deNO(x) activity is inexorably linked with occupancy of the zeolite 6r.
