Abstract
•NO was concentrated on Fe(II) in zeolites even in the coexistence of excess oxygen.•Al-rich beta zeolite enabled Fe(II) to hold NO as much as NO/Fe(II) molar ratio of 2.•Al distribution in zeolite is a key to hold ions in a coordinately unsaturated state.
Fe(II)-beta zeolites with a Si/Al molar ratio of 5, synthesized in the absence of an organic structure-directing agent, showed remarkably efficient NO chemisorption, as compared to conventional Si-rich beta zeolites (Si/Al = 12–20) and common zeolites such as A-type zeolite, ZSM-5, and faujasite.
