Abstract
Disclosed are a hydrocarbon adsorption and desorption complex that reduces emission of hydrocarbon from vehicle exhaust gas and improves hydrothermal stability of a device, and a method for preparing the same. The hydrocarbon adsorption and desorption complex may have improved adsorption ability of the hydrocarbon as metal ions are bound to a gas adsorbing portion containing aluminum, and may have improved hydrothermal stability as a reinforcing portion made of silica is formed on a surface of the gas adsorbing portion.
