What is the Significance of Alloying in Catalysis?
Alloying involves combining two or more metals to create a composite material with enhanced catalytic properties. Bimetallic or multimetallic catalysts can exhibit synergistic effects, where the combination of metals leads to superior activity, selectivity, and stability compared to individual metals. For example, alloying platinum with ruthenium can improve the catalyst's resistance to carbon monoxide poisoning in fuel cells.
