Abstract
•An advanced catalyst Rh/CZ2 was prepared with the assistance of monoethanolamine.•Rh/CZ2 displays higher hydrothermal aging resistance than conventional Rh/CZ1.•Higher dispersion and more active states of Rh are maintained for aged Rh/CZ2a.•Rh/CZ2 exhibits superior three-way catalytic performance regardless of aging.
