The design of multifunctional catalysts involves a deep understanding of the catalytic processes and the interactions between different active sites. Some common strategies include: - Hybrid Catalysts: Combining different catalytic materials, like metals and oxides, to create a catalyst with multiple active sites. - Core-Shell Structures: Designing catalysts with a core material that provides one catalytic function and a shell that offers another. - Bimetallic Catalysts: Using two different metals that can work together to provide a multifunctional catalytic surface. - Support Materials: Utilizing materials like zeolites or metal-organic frameworks (MOFs) that can host various active sites within their structures.
