In summary, chemists and chemical engineers use tools such as density functional theory, Phase Field modeling, and computational multiphysics to develop new catalysts with desired properties. These methods involve studying known catalysts and using computational tools to inform experiments, with the results of experiments then being used to refine the models. This allows for the exploration of different combinations of elements to find the most effective catalysts for specific applications.

What methodology is used for developing new catalysts with desired properties?

To give some real world example, today chemists and chemical engineers try to find electrocatalysts needed for reduction of oxygen in hydrogen fuel cells and for oxidation of water in water electrolysis needed to make both more energy efficient.

When trying to do so, where do they start from?

Catalysis is well-established; it's been known for decades, and the nature of various catalysts are already known. However, physical chemists and chemical physicists now use tools like density functional theory (DFT) and Phase Field modeling (PFM).

For example, https://aiche.onlinelibrary.wiley.com/doi/abs/10.1002/aic.14401

PFM - https://www.osti.gov/pages/servlets/purl/1343950

Computational multiphysics is another approach.

Edit/update: I should add that there are only so many elements, and more so, a limited number of transitional metal elements that are practical, usually in the form of metal oxides, but one can also find metal or intermetallic combinations. So, we can try different combinations based on what we know and enhance the understanding with computational tools, which inform experiments, with experiments feeding back to modeling.
