【央视新闻】我国科学家首次呈现纳米尺度黄金形成的动态过程

Core Insights - The research team from the Guangzhou Institute of Geochemistry has utilized in-situ liquid-phase transmission electron microscopy to reveal the dynamic process of gold nanoparticle formation on the surface of pyrite for the first time [1] - A new mechanism for gold precipitation induced by pyrite has been proposed, highlighting the presence of a "dense liquid layer" at the pyrite-water interface that acts as a "nanoscale factory" for gold nucleation and growth, even in extremely low gold concentration fluids [1][2] Group 1 - The study challenges the traditional view that gold primarily originates from deep hydrothermal fluids, opening new pathways for understanding the mineralization process driven by nanoparticles in nature [2] - The findings provide critical insights into the formation process of gold on pyrite surfaces, which is essential for understanding the genesis of high-grade gold deposits [1] - The mechanism has practical implications for interface control in green gold leaching processes [2]
