New research challenges the traditional understanding of gold's chemical inertness, revealing that it's not an inherent property of gold atoms but rather due to the protective surface structure of gold crystals. The study explains why gold nanoparticles can act as catalysts while bulk gold appears inert, solving a long-standing paradox in chemistry. This discovery could lead to new applications in catalysis and materials science.
Background
Gold has long been considered chemically inert due to its electron configuration, but this has been challenged by the discovery that gold nanoparticles exhibit catalytic properties. The new research provides a more nuanced understanding of gold's reactivity at different scales.
