What are the Challenges in Using Multimetallic Catalysts?
Despite their advantages, multimetallic catalysts pose certain challenges:
- Complexity in Synthesis: The preparation methods can be complex and require precise control over the composition and distribution of metals. - Characterization: Identifying and characterizing the active sites within multimetallic catalysts can be challenging due to the presence of multiple metals. - Cost: The use of precious metals in some multimetallic catalysts can be cost-prohibitive. - Stability: While generally more stable, some multimetallic catalysts can still suffer from issues like sintering and leaching of metals.
