摘要

Promotional effects of Ce⁴⁺, La³⁺ and Nd³⁺ incorporations on FeCu₂O_3.5/ATS for decomposing N₂O were investigated. Results showed that all the ions especially La³⁺ can dramatically improve the catalytic performance. FeCu₂La_1.5O_x/ATS, the optimal catalyst, can decompose 100% N₂O at 550°C. The formed perovskite-type LaFeO₃ and spinel-type CuLa₂O₄ largely improved catalytic performance. The ion modification increased N₂O adsorption capacity, and La³⁺-doped catalyst enhanced desorption ability of surface oxygen. Both effects can accelerate the rate-determine steps of N₂O decomposition reaction, promote catalytic performance. Moreover, the supported catalysts studied were economic efficiency for application.
