Solid catalysts operate by providing a surface on which reactants can adsorb, react, and desorb. This process involves several steps:
1. Adsorption: Reactants are adsorbed onto the catalyst's surface. 2. Reaction: Adsorbed reactants undergo a chemical reaction facilitated by the catalyst. 3. Desorption: Products are released from the catalyst's surface.
The efficiency of a solid catalyst depends on factors such as surface area, porosity, and the nature of active sites.
