Electric Double Layer at the Rutile (110) Surface. 1. Structure of Surfaces and Interfacial Water from Molecular Dynamics by Use of ab Initio Potentials

Popis výsledku v původním jazyce

A recently developed force field for interactions of water molecules with the (110) surface of rutile (alpha-TiO2) has been generalized for atomistically-detailed molecular dynamics simulations of the interfacial structure of the uncharged mineral surface in contact with liquid SPC/E water at 298K and 1 atmosphere, and negatively-charged surfaces in contact with SPC/E water containing dissolved electrolyte ions (Rb+, Sr2+, Zn2+, Na+, Ca2+, Cl-). Both hydroxylated (dissociative) and nonhydroxylated (associative) surfaces are simulated. For all simulated properties, including space-dependent diffusivity of water molecules, the influence of the interface is negligible beyond distances of about 15 ? from the surface. Increasing the temperature to 448K while maintaining the density at the liquid-vapor saturated condition had minimal effect on the interfacial structure and electrostatic properties.
