The doping of C and N into meso-structured TiO2 increases the number of surface defects which could improve the absorption of oxygen, tune the metal-support interaction and promote the catalytic activities for CO oxidation.

Strong Metal Support Interaction

Platinum nanoparticles (Pt NPs) immobilized on a N-doped graphene@Al2O3 hybrid support (Al2O3@CNx) were synthesized and exhibit superior catalytic activity for low temperature CO oxidation, due to a strong metal–support interaction between Pt NPs and the N-doped.

Incipient Wetness

Cu/H-Sep and Cu-Fe/H-Sep samples were prepared by the incipient wetness impregnation method. These catalysts were characterized by means of XRF, XRD, BET, XPS, and H2-TPR techniques, and their catalytic activities were performed by the SCR of NO with propylene. The results show that the Cu-Fe/H-Sep catalyst exhibited the best performance in the C3H6-SCR of NO. After investigation by H2-TPR, XRD and XPS, the result showed that the higher reducibility, more amount of isolated Cu2+, higher dispersion of copper species, and stronger metal-support interaction were responsible for the excellent catalytic activity of Cu-Fe/H-Sep.
