Catalyst modifications involve altering the physical or chemical properties of a catalyst to enhance its performance, selectivity, or stability. These modifications can be achieved through various approaches, such as:
- Doping: Adding small amounts of foreign elements to the catalyst to improve its activity or selectivity. - Surface Treatments: Techniques like plasma treatment or acid/base washing to modify the surface properties. - Alloying: Combining different metals to create bimetallic or multimetallic catalysts with enhanced properties. - Support Modification: Altering the support material to improve its interaction with the active phase or enhance its dispersion.
