Preparation of Mesoporous La1-xSrxMnO3 Catalysts via COK-12 Nano-Casting Method

Abstract

Abstract: Perovskite-type catalysts show promising potential in the purification of automobile exhaust. This paper discussed the synthesis of mesoporous material COK-12 using surfactant P123 as a soft template and inexpensive sodium silicate as the silicon source under nearly neutral conditions. Building on this, the mesoporous COK-12 was modified with p-xylene as a swelling agent, resulting in large-pore, ordered mesoporous materials. Subsequently, for the first time, modified mesoporous materials were used as templates for the preparation of mesoporous La_0.8Sr_0.2MnO₃ catalysts through nano-casting combined with the sol-gel method. The results demonstrate that the catalyst synthesized at 550 ℃ possesses a larger specific surface area (72.11 m²/g) and the highest molar ratio of Mn⁴⁺/Mn³⁺ and O_ads/O_lat on the surface. Additionally, CO catalytic performance tests of samples indicate that those synthesized at 550 ℃ exhibit the best catalytic activity and excellent high-temperature stability. Their characteristic temperatures T₅₀ and T₉₀ are 180 and 218 ℃, respectively.

Key words: COK-12, mesoporous material, nano-casting method, sol-gel method, CO catalysis
