Ni‐CeO2/AlSBA‐15 With High H2 Production Efficiency and Potent Coking Resistance in Methane Steam Reforming (SRM): Study the Synergistic Effects of Ni Dispersion, Redox Property and Surface Alkalinity

Carbon and Hydrogen, EarlyView.
The active metallic Ni surface, redox property, and surface alkalinity are the main factors to determine the activity and anti‐coking ability of the studied catalysts for the SRM reaction. Ni‐CeO2/AlSBA‐15 achieves the highest Ni dispersion as well as the largest number of surface‐active oxygen and alkaline sites, thus getting the best H2 production ...
