  "textContent": "The disclosure provides a platinum-containing three-way conversion (TWC) catalyst, and a system for treating an exhaust gas stream from a gasoline engine using the TWC catalyst. The system is configured to introduce controlled quantities of hydrogen gas into the exhaust gas stream upstream of the platinum-containing TWC catalyst article during a cold-start period. Further provided are related methods of treating such exhaust streams. Such systems and methods are useful in reducing a level of one or more of hydrocarbons, carbon monoxide, and nitrogen oxide in a gaseous exhaust stream from a gasoline engine.",
