Catalyst design for heavy-duty diesel combustion engines

Described is related to a nano-structured composite absorber for air detoxing and deodoring at ambient temperature to prevent harmful chemicals in the air from damaging human health. The nano-structured composite absorber consists of nano-porous carbon, zeolites with nano-sized pores and at least 1 other component chosen from nano-porous rare earth oxides and nano-sized catalysts. The synergetic action of those nano-structured components can effectively remove toxic chemicals including, but not limited to formaldehyde, benzene, toluene, xylene, propene, butadiene, acetone, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, ammonia, alcohols, chlorine, mercaptans, as well as malodors, such cigarette smoke, net/fish/poultry odors and bathroom/toilet smells.

Nano-structured composite absorber for air detoxing and deodoring

Disclosed are, inter alia, methods of forming coated substrates for use in catalytic converters, as well as washcoat compositions and methods suitable for using in preparation of the coated substrates, and the coated substrates formed thereby, which in some cases use iron-exchanged zeolite particles that provide enhanced performance such as lower light-off temperatures and lower pollutant levels in exhaust gases. The catalytic material is prepared by a plasma-based method, yielding catalytic material with a lower tendency to migrate on support at high temperatures, and thus less prone to catalyst aging after prolonged use. Also disclosed are catalytic converters using the coated substrates, which have favorable properties as compared to catalytic converters using catalysts deposited on substrates using solution chemistry. Also disclosed are exhaust treatment systems, and vehicles, such as diesel vehicles, particularly light-duty diesel vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.

Advanced catalysts for automotive applications

The present disclosure relates to a substrate comprising nanomaterials for treatment of gases, washcoats for use in preparing such a substrate, and methods of preparation of the nanomaterials and the substrate comprising the nanomaterials. More specifically, the present disclosure relates to a substrate comprising nanomaterial for three-way catalytic converters for treatment of exhaust gases.

Three-way catalytic converter using nanoparticles

A nanoparticle comprises a nano-active material and a nano-support. In some embodiments, the nano-active material is platinum and the nano-support is alumina. Pinning and affixing the nano-active material to the nano-support is achieved by using a high temperature condensation technology. In some embodiments, the high temperature condensation technology is plasma. Typically, a quantity of platinum and a quantity of alumina are loaded into a plasma gun. When the nano-active material bonds with the nano-support, an interface between the nano-active material and the nano-support forms. The interface is a platinum alumina metallic compound, which dramatically changes an ability for the nano-active material to move around on the surface of the nano-support, providing a better bond than that of a wet catalyst. Alternatively, a quantity of carbon is also loaded into the plasma gun. When the nano-active material bonds with the nano-support, the interface formed comprises a platinum copper intermetallic compound, which provides an even stronger bond.

More specifically, the present disclosure relates to a coated substrate comprising nanoparticle catalysts and NOstorage materials for lean NOtrap (LNT) systems, useful in the treatment of exhaust gases.

Disclosed are, inter alia, methods of forming coated substrates for use in catalytic converters, as well as washcoat compositions and methods suitable for using in preparation of the coated substrates, and the coated substrates formed thereby.
