The perovskite material requires metal oxides that supports to enhance the catalytic activity which is cost effective and Heat resistance that is increased to use by many scientists.
In this study, the One-dimensional perovskite arrays are prepared by Anodic Aluminum Oxide(AAO). The different ratio of LaFe1-xMnxO3 (x=0, 0.5, 1) were characterized using in situ FTIR (DRIFT) which can observe the adsorption of carbon monoxide and nitrogen oxides on the transition of perovskite-type Catalyst. And also we have discussed the gas phase reaction by using Gas Cell-FTIR, which not only observe the NO, NO2 , N2O4, also observe the N2O , N2O3. Further, we studied the changes with different temperature. Finally, we have calculated the CO conversion rate by the GC with TCD.
The as-prepared perovskite-type LaFe1-xMnxO3 catalyst was observed by X-ray Diffraction (XRD) to know the structure of the perovskite and its crystalline. The surface morphology of perovskite materials with high magnification and low magnification was confirmed by SEM and FESEM respectively. The EDS to ensure the element content in the perovskite material. The Photoluminescence was used to identify the energy band gap of perovskite material.
