In this paper, Pd-only catalysts were prepared with honeycomb ceramic monol.

Comparing with Pt and Rh, Pd is more abundant in resource, cheaper and better at light-off performance among the three kinds of rare-mental active components of TWC catalyst, and the Pd-only catalyst is playing more and more important role in the automotive emission control materals.

The analysis of key point in the production of hydrogen peroxide with Pd catalyst;

The latest progress of support modification, new supports(including macromolecular support and alumina support with nano-fiber shape), cocatalysts and new preparation technology of the catalysts in the research on the novel Pd catalysts for anthraquinone hydrogenation in recent years is reviewed.

Through the experiment and comparison of regenerating methods using steam,aromatic hydrocarbon and oxidizing solution for Pd catalyst used in the hydrogen peroxide production by anthraquinone process,recommends Pd catalyst regenerating method using oxidizing solution could being applied in the industrial hydrogen peroxide production.

Summary on palladium catalyst in hydrogen peroxide production by anthraquinone process;

Recent advances in palladium catalysts for aryl chlorides coupling reaction;

Rational operation of palladium catalyst in hydrogen peroxide manufacture;

The major effectors of three-way catalytic performance of Pd-only automobile exhaust catalysts were presented and discussed,which are the selection of additives,the loading methods of Pd,the preparation parameters and so on.
