A review of catalyst modifications for a highly active and stable hydrogen production from methane

In the thermo-catalytic hydrogen production from methane, catalyst deactivation is a major issue for the industrial applications. In this review, six modification strategies to achieve a robust catalyst have been discussed in category, including preparation methods, metal-support interaction, support confinement, surface acidity and basicity, oxygen defects and alloys. In addition, the reaction mechanisms of seven methane-involved reactions and three deactivation mechanisms (poisoning, sintering and coking) are illustrated. Moreover, a critical analysis of the synthesis-structure-performance relationship is provided. Finally, conclusive remarks and prospects are proposed. & COPY; 2022 Hydrogen Energy Publications LLC.
