    Abstract: A method of producing a catalyst comprises generating an aerosolized flow of catalyst support particles, heating a catalytically active compound precursor to produce a catalytically active compound precursor vapor, contacting the aerosolized flow of catalyst support particles with the catalytically active compound precursor vapor, and condensing the catalytically active compound precursor onto the catalyst support particles to produce the catalyst comprising catalytically active compound deposited on surfaces of the catalyst support particles. The method may further comprise aerosolizing a catalyst support precursor mixture, drying the aerosolized catalyst support precursor mixture in a first heating zone to form an aerosolized flow of catalyst support particles, and contacting the catalyst support particles with a catalytically active compound precursor vapor in a second heating zone to form the catalyst comprising the layer of the catalytically active compound deposited on surfaces of the catalyst of catalyst support particles.

    Abstract: Synergies resulting from combinations of catalyst systems including Copper-Manganese material compositions and PGM catalysts are disclosed. Variations of catalyst system configurations are tested to determine most effective material composition, formulation, and configuration for an optimal synergized PGM (SPGM) catalyst system. The synergistic effect of the selected SPGM catalyst system is determined under steady state and oscillating test conditions, from which the optimal NO/CO cross over R-value indicates enhanced catalytic behavior of the selected SPGM catalyst system as compared with current PGM catalysts for TWC applications. According to principles in the present disclosure, application of Pd on alumina-based support as overcoat and Cu-Mn spinel structure supported on Nb2O5-ZrO2 as washcoat on suitable ceramic substrate, produce higher catalytic activity, efficiency, and better performance in TWC condition, especially under lean condition, than commercial PGM catalysts.
