Though the model results are obtained for a Pt(111) electrode in HClO4-based solution, I do not see principal difficulties in applying it to the alkaline regime, to other electrolyte solution with specifically adsorbing anions such as sulphate and halide ions, and to stepped Pt electrodes. In these new scenarios, the model may need to be extended by including new specific adsorption and/or chemisorption processes, and to be re-parameterized case-by-case.
