Recent Advances in the Catalysts for Hydrogen Production via Ethanol Steam Reforming

Abstract Hydrogen is regarded as an important energy carrier for the global energy transition. Hydrogen production from ethanol steam reforming (ESR) has the advantages of renewable feedstock and high system energy efficiency, which is deemed to be an attractive hydrogen production process. However, the rational design of ethanol steam reforming catalysts remains challenging in terms of enhancing hydrogen selectivity and inhibiting catalyst deactivation. In this review, we provide a comprehensive overview of recent research on the reaction mechanism of the ESR process and catalyst modification with an emphasis on the correlation between the type of active metals, promoters, metal‐support interaction, catalyst structures, preparation strategy, and corresponding catalytic performance. This work provides valuable guidance for the optimization of ESR catalysts toward hydrogen production.
