碘化银类表面上的非均匀冰成核

Heterogeneous ice nucleation on silver-iodide-like surfaces

Guillaume Fraux, Jonathan P. K. Doye

摘要:

我们试图模拟冰在模型碘化银表面上的非均质成核,发现在Ag+终止的基面上的冰成核和生长相对容易,但从未看到在I-终止的基面或棱柱和正常面上的成核。水分子强烈吸附到Ag+终止d面,得到一个有序的六方冰状双层,然后作为进一步的冰生长的模板。

英文摘要:

We attempt to simulate the heterogeneous nucleation of ice at model silver-iodide surfaces and find relatively facile ice nucleation and growth at the Ag+ termi nated basal face, but never see nucleation at the I- terminated basal face or the prism and normal faces. Water molecules strongly adsorb onto the Ag+ terminate d face to give a well-ordered hexagonal ice-like bilayer that then acts as a template for further ice growth.
