Adsorption on solids - homogeneous/heterogeneous surface definition
Homogeneous surface is the surface where we can (in the context of the scenario, like the purpose and required/available resolution and sensitivity) neglect any surface variability. Otherwise, the surface is heterogeneous.
It is important to say it is relative evaluation. For a set of surfaces, it can reach both extremes like "everything is homogeneous" to "everything is heterogeneous".
A visually homogeneous surface can be considered heterogeneous when evaluated by the enough zooming-in optical or electron microscope.
A visually heterogeneous surface can be considered homogeneous when evaluated from far enough or with low resolution or sensitivity for differences.
