In this paper, sodium bentonite, zeolite and other natural minerals are used to make adsorption materials, and physical and chemical adsorption are combined to improve the adsorption efficiency of NO x . The adsorbents were modified by loading additives with high catalytic capacity for NO. Results showed that the improved adsorbent has high adsorption to NO, making NO easy to be oxidized into NO 2 by the loaded metal oxides, thus NOx can be highly adsorbed and purified at room temperature.
