Abstract | 采用原位X射线衍射法对高温下不同钠盐修饰的Mn/SiO2催化剂物相结构进行了研究.结果表明,反应温度下催化剂表面的钠盐处于熔融的无定形态,提高了Mn2O3活性中心在甲烷氧化偶联反应中的催化活性. Sodium salt-modified Mn/SiO2 catalysts have been characterized by in situ X-ray diffraction. The results indicate that the low melting point sodium salts exhibit amorphous features under reaction conditions and they are good promoters for the Mn/SiO2 catalyst for the oxidative coupling of methane. |
