Several types of scaling relations have been identified in catalysis:
1. Adsorption Energy Scaling Relations: These are the most common and relate the adsorption energies of different adsorbates on a catalyst surface. For instance, the adsorption energy of nitrogen can be predicted by its relation to the adsorption energy of oxygen. 2. Transition State Scaling Relations: These involve the energies of transition states in catalytic reactions and their relationship to adsorption energies. 3. Activity Scaling Relations: These relate the overall catalytic activity of a material to its adsorption or transition state energies.
