Ziff–Gulari–Barshad model

The Ziff–Gulari–Barshad (ZGB) model is a theoretical framework used to study surface phenomena, particularly in catalysis and reaction-diffusion processes on surfaces. Proposed in the 1980s by Robert M. Ziff, Steven Gulari, and Robert A. Barshad, the model specifically addresses the dynamics of chemical reactions occurring on a two-dimensional lattice representing a solid surface.
