摘要：

Supported metal electrocatalysts with appropriate metal-support interactions (MSIs) show great potential for heterogeneous catalysis, however, precisely tuning the interactions at an atomic level remains a significant challenge. In this work, single-atom Co-N-4 sites are introduced to tailor the interfaces between PtIr alloy clusters and carbonaceous substrates, thereby establishing highly active and stable catalysts toward hydrogen oxidation reaction (HOR) in alkaline electrolytes and realizing atomically MSIs modulation. The experimental and theoretical results unveil that the formation of r...
