Contact Interaction in an M–SiO2 (M = Metal Catalyst for Nanowhisker Growth) System

Contact Interaction in an M–SiO2 (M = Metal Catalyst for Nanowhisker Growth) System We have studied contact interaction effects and wettability in M–SiO2 (M = metal catalyst for nanowhisker growth) systems. The results demonstrate that the wettability of SiO2 by the metal catalysts for nanowhisker growth (Au, Ni, Cu, and Sn) improves with a decrease in the first ionization potential of their atoms and is determined by dispersion interaction with the oxide surface. The interaction of the metal atoms with the O2– anions of the oxide is responsible for the development of cohesion between the liquid metal and SiO2 on the interface. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Inorganic Materials Springer Journals

Abstract

We have studied contact interaction effects and wettability in M–SiO2 (M = metal catalyst for nanowhisker growth) systems. The results demonstrate that the wettability of SiO2 by the metal catalysts for nanowhisker growth (Au, Ni, Cu, and Sn) improves with a decrease in the first ionization potential of their atoms and is determined by dispersion interaction with the oxide surface. The interaction of the metal atoms with the O2– anions of the oxide is responsible for the development of cohesion between the liquid metal and SiO2 on the interface.
