Abstract

Nanoporous membranes based on anodized aluminum oxide are prepared with atomic level control of pore dimensions and pore wall compositions by atomic layer deposition and are under investigation for use in catalysis. Simulation and modeling help to understand reactivity in confined geometry and to develop rational design of these new materials. In this context, we present results of molecular dynamics simulations of amorphous aluminum oxide surfaces. The surface structure is discussed in terms of density profiles, bond angle distributions and coordination numbers of surface atoms.
