The present disclosure relates to a catalyst for NOx removal. In some embodiments, the catalyst comprises a support comprising at least one selected from the group consisting of TiO, AlO, SiO, ZrO, CeO, zeolite, TiOand WO, and combinations thereof, and catalytically active components supported on the support. The catalytically active components comprise vanadium, antimony and at least one further component selected from the group consisting of silicon, aluminum and zirconium.

Supported catalyst, monolithic selective catalytic reduction (SCR) catalyst, preparation method therefor, and method for nitrogen oxides removal

Aspects of the invention pertain to catalytic articles and methods of making catalytic articles comprising a first catalytic coating comprising a platinum group metal, wherein the first catalytic coating is substantially free of Cu, Ni, Fe, Mn, V, Co, Ga, Mo, Mg, Cr and Zn; a second catalytic coating comprising a non-PGM metal, wherein the second catalytic coating is substantially free of any platinum group metal; and one or more substrates, wherein the first catalytic coating is separated from the second catalytic coating, optionally with a barrier layer.

Catalytic articles containing platinum group metals and non-platinum group metals and methods of making and using same

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.
