Enhanced catalytic performance of a PdO catalyst prepared via a two-step method of in situ reduction–oxidation.

A supported PdO nanocatalyst prepared by a facile in situ reduction process followed by an oxidation step showed significantly enhanced activity for the removal of pollutants from natural gas vehicles. The excellent catalytic performance is mainly due to high dispersion of the uniform PdO nanoparticles generated during the novel two-step method. [ABSTRACT FROM AUTHOR]
