    Impact of trace noble metals on the catalytic performance of LaNiMgO towards methane dry reforming حسب Mohamed, Assem T.

    منشور في 2024
    "…In addition, the reactor was blocked in case of LaNiMgO-Pd after about 54h.Excluding Pd, the enhancement of noble metals was assigned to the formation of noble metal-rich Ni surfaces, which suppressed the oxidation of nickel and enhanced the gasification of deposited coke. In addition, the presence of noble metals at the Ni surface afforded a high density of adsorbed oxygen species, which enhanced coke gasification and consequently decreased the extent of deactivation of the catalysts by coke formation. …"
