How are Bimetallic and Trimetallic Catalysts Prepared?
The preparation methods for bimetallic and trimetallic catalysts vary widely. Common techniques include _co-precipitation_, _impregnation_, and _alloying_. Each method has its advantages and limitations, and the choice depends on the desired properties of the catalyst. For instance, co-precipitation allows for a more uniform distribution of metals, while impregnation can be used to introduce metals onto a pre-existing support material.
