Unveiling the Catalytic Potential of Topological Nodal-Line Semimetal AuSn₄ for Hydrogen Evolution and CO₂ Reduction.

ABSTRACT: In recent years, the correlation between the existence of topological electronic states in materials and their catalytic activity has gained increasing attention, due to the exceptional electron conductivity and charge carrier mobility exhibited by quantum materials. However, the physicochemical mechanisms ruling catalysis with quantum materials are not fully understood. Here, we investigate the chemical reactivity, ambient stability, and catalytic activity of the topological nodal-line semimetal AuSn₄. Our findings reveal that the surface of AuSn₄ is prone to oxidation, resulting in the formation of a nanometric SnO₂ skin. This surface oxidation significantly enhances the material's performance as a catalyst for the hydrogen evolution reaction in acidic en
