Abstract: Disclosed herein are emission treatment systems comprising an oxidation catalyst composition in fluid communication with an exhaust gas stream emitted from an engine that combusts both hydrocarbon fuel and hydrogen; and optionally, at least one selective catalytic reduction (SCR) composition and/or at least one three-way conversion (TWC) catalyst composition, combustion systems comprising the same, and method of treating an exhaust gas stream, such as, e.g., an exhaust gas produced by combusting hydrogen fuel during a cold-start period, using the same.
