Platinum‐containing catalysts for enhanced hydrogen production via methanol steam reforming

Abstract The growing demand for sustainable hydrogen production has spurred extensive research into methanol steam reforming (MSR). This review focuses on platinum‐containing catalysts, emphasizing their role in enhancing hydrogen production via MSR. Key findings demonstrate platinum's pivotal role as an active component, with significant contributions from support materials (e.g., TiO 2 , Al 2 O 3 , ZnO, CeO 2 , MoC) and promoters (e.g., Ru, In) in improving catalytic activity, selectivity, and stability. Notably, platinum‐based catalysts have shown high hydrogen selectivity, with some achieving 100% H 2 selectivity. The performance of these catalysts is influenced by reaction temperature, with higher temperatures generally increasing conversion but not always enhancing H 2 selectivity. Molybdenum carbide‐based catalysts and specific composite oxides exhibit great promise in enhancing catalyst performance. This review highlights the potential of platinum‐containing catalysts for efficient MSR and outlines areas requiring further research, including metal‐support interactions, catalyst deactivation, low‐temperature operation, and techno‐economic considerations. Future efforts should focus on optimizing platinum catalyst design and promoter selection for real‐world applications.
