摘要：
The catalytic activities of strontium substituted La0.7Sr0.3MnO3 type perovskite catalysts for NO reduction using H2 as reducing agent has been studied, which is further improved by incorporation of Pt outside (0.1 wt.%Pt/La0.7Sr0.3MnO3) and inside (La0.7Sr0.3Mn0.97Pt0.03O3) the perovskite lattice structure. Pt shows excellent enhancement in catalytic selectivity towards N2 when supported on the perovskite. The catalysts were characterized using thermo-gravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and specific surface area. Catalysts evaluations were carried out using thermo-gravimetric analysis coupled with mass spectra (TG-MS).
