Despite its benefits, physisorption has certain limitations:
1. Weak Interaction: The weak van der Waals forces mean that physisorption is not suitable for reactions requiring strong adsorption. 2. Temperature Sensitivity: Since physisorption is favored at low temperatures, it may not be effective in high-temperature catalytic processes. 3. Reversibility: The reversible nature of physisorption can lead to desorption of reactants, reducing the efficiency of the catalytic process.
