Described are catalytic articles comprising a substrate having a washcoat on the substrate, the washcoat containing a catalytic component having a first average (D50) particle size and a functional binder component having a second average (D50) particle size in the range of about 10 nm to about 1000 nm, wherein the ratio of the first average (D50) particle size to the second average (D50) particle size is greater than about 10:1. The catalytic articles are useful in methods and systems to purify exhaust gas streams from an engine.

Nano-sized functional binder

The principles and embodiments of the present invention relate generally to systems and methods for applying a catalytic coating to the outwardly facing edges of the cell walls of a catalytic substrate to reduce the amount of soot that accumulates at the entrances of the substrate cells that can increase back pressure and reduce the flow of exhaust gases through the substrate.

Apparatus and process for face painting substrates with PGM and base metal solutions

A catalyst material including a catalyst carrier including a porous alumina support and a hindrance layer on the alumina support, the hindrance layer comprising one or more barium sulfate, strontium sulfate, zirconium sulfate, and calcium sulfate is described. The catalyst carrier further includes a rare earth oxide. The catalyst material can further comprise a platinum group metal oxide. The hindrance layer may prevent the rare earth oxide from forming a complex with the support. The catalyst material is useful for methods and systems of abating pollutants from automotive exhaust gas.
