By using a modified coimpregnation method, a multicomponent Pd&Bi(1.4)/TiO2-N catalyst with hierarchical metal–metal oxide interfaces was prepared that showed a better activity and stability for low-temperature CO oxidation than Pd/TiO2-N and Pd/P25. The structural characterization and catalytic activity results proved that an appropriate amount of Bi species has a clear promoting effect on the Pd-based catalyst. Particularly, the catalyst can be mass-produced conveniently, which may be beneficial for versatile reactions and practical applications.
