Abstract:The elimination of toluene is an obligatory target with
increasing
VOC emission in recent years. This study successfully prepared a single-atom
Ir catalyst (Ir1/CeO2) by a simple incipient
wetness impregnation method, confirmed by in situ CO DRIFTS and AC-HAADF-STEM.
Compared to the cluster Ir catalyst (Ir/CeO2-C), Ir1/CeO2 exhibited excellent catalytic performance,
stability, and water resistance for the oxidation of toluene. By Raman,
H2-TPR, O2-TPD, and XPS experiments, abundant
oxygen defects and a unique … Show more
