How Does Catalyst Structure Affect Its Performance?
The performance of a catalyst is intricately linked to its structure. Key factors include:
Surface Area: A higher surface area provides more active sites, enhancing the catalyst's activity. Particle Size: Smaller particles increase the surface-to-volume ratio, offering more active sites per unit mass. Crystal Structure: The arrangement of atoms in the catalyst's crystal lattice can affect its catalytic properties. For instance, different crystal facets may exhibit varying catalytic activities. Metal-Support Interaction: The interaction between the active metal and the support material can influence the electronic properties and dispersion of the active sites.
