Precise design and synthesis of Pd/InO@CoO core-shell nanofibers for the highly efficient catalytic combustion of toluene.

In this work, Pd/InO@CoO core-shell nanofibers, CoO@Pd/InO core-shell nanofibers and Pd/InO/CoO nanofibers with different morphologies have been successfully synthesized for the catalytic combustion of toluene. Among them, the Pd/InO@CoO core-shell sample is novel and composed of Pd/InO nanotube cores, CoO nanocubes and CoO nanoparticle shells derived from ZIF-67. On the contrary, the CoO@Pd/InO core-shell catalyst is assembled by CoO nanocube cores and Pd/InO nanotube shells.
