The primary sources of intrinsic variability include:
1. Atomic Structure: Variations in the atomic arrangement can lead to differences in catalytic performance. For instance, defects and dislocations in the crystal lattice can act as active sites or inhibit catalytic activity. 2. Surface Morphology: The shape and size of catalyst particles can significantly affect their surface area and the availability of active sites. 3. Electronic Properties: The electronic structure of a catalyst, including its band gap and electron density, can influence its ability to adsorb and activate reactants.
