Effect of Fe substitution on the partial oxidation of methane to syngas over La0.7Sr0.3Co1−yFeyO3−δ perovskites

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

In this research, a series of La0.7Sr0.3Co1−yFeyO3−δ (y = 0.0–0.4) was successfully synthesized by a solidstate reaction method and syngas production studies were performed using gas chromatography. Thermogravimetric analysis characterized the concentration of Fe3+, which gave a low H2/CO ratio over La0.7Sr0.3Co1−yFeyO3−δ without the presence of molecular oxygen. All samples possessed a purely rhombohedral structure. The incorporation of more Fe increased the lattice parameter and changed XRD peaks of the La1−xSrxCo0.8Fe0.2O3 from sharp and single to double. |
