How Does Mechanical Grinding Affect Catalyst Properties?
Mechanical grinding affects the physical and chemical properties of catalysts in several ways:
1. Increased Surface Area: By grinding the material into finer particles, the surface area is increased, which allows for more active sites for catalytic reactions. 2. Phase Transformation: Mechanical grinding can induce phase transformations in materials, potentially leading to the formation of new, more active catalytic phases. 3. Defect Creation: The mechanical force can introduce defects in the crystal structure of the material, which can act as active sites for catalysis. 4. Homogeneous Mixing: It allows for the homogeneous mixing of different components, which can be crucial for the formation of composite catalysts.
