Strategic Roadmap for Noble Metal-Free Catalysts in Acidic Oxygen Evolution. (IMAGE)
Caption
This schematic illustrates the comprehensive framework for advancing non-noble metal catalysts in acidic oxygen evolution reactions (OER). It highlights three core research questions—mechanism of activity expression, causes of poor stability, and strategies for stability improvement—alongside six key catalyst categories, including polymetallic oxides, doped systems, and single-atom catalysts. Together, these elements chart a pathway toward efficient and durable hydrogen production without reliance on scarce noble metals.
