Adsorption of interacting particles on highly correlated heterogeneous surfaces is studied through grand canonical Monte Carlo simulation and the effective substates approximation in the framework of the lattice-gas model. The adsorptive surface potential has been characterized by patches of weak and strong adsorbing sites arranged in a deterministic chessboard structure, with square, triangular or hexagonal geometry. The effects of heterogeneity and nearest-neighbor adsorbate–adsorbate interactions on the adsorption process are analyzed for square, honeycomb and triangular geometries and different patch sizes.
