By using a modified coimpregnation method, a multicomponent Pd&Bi(1.4)/TiO 2 ‐N catalyst with hierarchical metal–metal oxide interfaces was prepared that showed a better activity and stability for low‐temperature CO oxidation than Pd/TiO 2 ‐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.
