• Using examples from surface science, we consider in this article problems of non-equilibrium pattern formation in reactive soft matter. An interplay of reaction, diffusion and energetic interactions between adatoms can produce a variety of non-equilibrium nanostructures, both stationary and traveling. These structures are similar to the patterns found in phase-separating binary mixtures under the influence of reactions. Because of their small sizes, such nanostructures are significantly affected by fluctuations. The derivation of meso-scopic stochastic equations for fluctuating concentrations, starting from the microscopic master equation of the lattice approximation, is discussed. Special attention is paid to surface chemical reactions involving a promoter species, where experimental observations are available.
