The selectivity of a catalyst, or its ability to produce a specific product over others, can also be influenced by particle size distribution:
Shape and Facet: Different particle sizes may expose different crystallographic facets, which can have varying catalytic properties. Reactant Access: Smaller particles may allow for better access of reactants to the active sites, influencing the pathway of the reaction. Size-Dependent Reactivity: Some reactions may preferentially occur on particles of a specific size.
