Influence of phase transition on pattern formation during catalytic reactions (Q1587684)

The paper presents the influence of the order of surface phase transitions on pattern formation during chemical reaction on mono-crystal catalysts. The co-oxidation on a platinum surface is considered. The model consists of two partial differential equations, one of which describes the dynamics of the surface state with the help of a Ginzburg-Landau potential. The stability analysis for plane waves is presented and the Benjamin-Feir unstable region is drawn. Results obtained by the numerical integration of the system are presented.
