A catalytic vessel for adsorbing catalytic metals, such as from automotive exhaust gases, and carrying out three-way catalysis includes an inlet at an upstream end, a plurality of catalytic chambers located downstream of the inlet, and an outlet. At least one of the catalytic chambers contains a plurality of sheet members preferably made of steel and adapted for deposition of a metal selected from the group of noble and non-noble metals, and more particularly from the group including platinum, rhodium, rhenium, palladium, and gold. The vessel may be used in a catalytic system which contains a liquid source of metal catalysts, such as a solution or a gasoline additive, from which the metal catalysts are added to a combustion system, and the catalytic vessel, which collects the metal catalysts and is a site for three-way catalytic conversion of starting materials such as automotive emissions to final products.

A catalytic vessel comprising: an outer shell having an inlet positioned at an upstream end of the shell, and an outlet positioned at a downstream end of the shell; and a working body located in the shell, the working body comprising a steel selected from the group consisting of low carbon and stainless steel, wherein the steel has an oxidized surface constructed and arranged for adsorption of metal catalysts from a gas phase, such that the working body is constructed and arranged to serve as a site which is replenishable in situ for carrying out three-way catalysis.
