論文摘要♡：As important precursors of crystalline phases, amorphous phases of minerals, especially carbonate-based minerals, have been attracting more and more interest in fundamental research and materials chemistry, as well as industrial applications. However, it is still challenging to largely and rapidly synthesize stable amorphous carbonate minerals without the assistance of stabilizers. In this paper, we report an ultrafast method for the high-yield, scale-up synthesis of amorphous carbonate mineral nanoparticles (CaCO3, MgCO3, SrCO3, and their hybrids) within 1 min through the fast diffusion of high-pressure carbon dioxide into ethanol. The present strategy not only allows for the massive production of pure and stable amorphous carbonates but also shows great potential in industrial uses like water treatment.
