Abstract:The
effectiveness of surface synergetic oxygen vacancy (SSOV) on
a catalyst has been proposed in the selective reduction of NO to N2 by CO. In this work, we prepared fresh CuMn2O4 spinel catalyst using the freeze-assisted sol–gel
method, and then engineered SSOVs through CO pretreatment (CO–CuMn2O4) at 250 °C. The catalytic performance of
the CO–CuMn2O4 catalyst showed significant
improvement, attributed to the presence of SSOVs, in comparison to
that of the fresh CuMn2O4 sample. Additionally,
our findings elu… Show more
