FIELD: chemistry.
SUBSTANCE: advanced catalyst includes a honeycomb structure with a nanoparticle on the honeycomb structure. The advanced catalyst used in diesel engines is a two-way catalyst. In both the two-way catalyst and a three-way catalyst, the nanoparticle includes an active nanomaterial and a nanosupport. The nanosupport is typically alumina. In the two-way catalyst, the active nanomaterial is platinum. In the three-way catalyst, the active nanomaterial is platinum, palladium, rhodium, or an alloy. The alloy is a platinum, palladium and rhodium alloy.
EFFECT: improved catalyst properties.
