Abstract
Disclosed are a hydrocarbon adsorption and desorption complex including zeolite with a controlled cation type and a preparation method therefor. The hydrocarbon adsorption and desorption complex exhibits excellent hydrocarbon adsorption and oxidation performance even at a temperature lower than a catalyst activation temperature by controlling the distribution of metal ions and metal oxides, and also exhibits excellent hydrocarbon adsorption and oxidation performance even in the presence of water, by being prepared through hydrothermal treatment.
