N 2 O is a greenhouse gas and a candidate oxidant. Volatile organic pollutants (VOCs) have caused great harm to the atmospheric ecological environment. Developing the technique utilizing N 2 O as the oxidant to oxidize VOCs to realize the collaborative purification has significant importance and practical value for N 2 O emission control and VOC abatement. Therefore, the study of N 2 O catalytic oxidation of tert-butanol based on zeolite catalysts was carried out. A series of molecular sieves, including FER, MOR, ZSM-5, Y, and BEA, were selected as the catalyst objects, and the 1.5% wt Fe and Co were, respectively, loaded on the zeolite catalysts via the impregnation method. It was found that the catalytic performance of BEA was the best among the molecular sieves. Comparing the catalytic performance of Fe-BEA under different load gradients (0.25~2%), it was found that 1.5% Fe-BEA possessed the best catalytic activity. A series of characterization methods showed that Fe 3+ content in 1.5% Fe-BEA was the highest, and more active sites formed to promote the catalytic reaction. The α-O in the reaction eventually oxidized tert-butanol to CO 2 over the active site. The Co mainly existed in the form of Co 2+ cations over Co-BEA samples; the 2% Co-BEA possessing higher amounts of Co 2+ exhibited the highest activity among the prepared Co-BEA samples.
