Dry impregnation is crucial for several reasons: 1. Uniform Distribution: It ensures the active species are uniformly distributed over the support, which is essential for achieving high catalytic activity and selectivity. 2. Pore Utilization: It maximizes the utilization of the pore structure of the support material, enhancing the surface area available for catalytic reactions. 3. Economic Efficiency: It is cost-effective as it uses minimal amounts of the precursor solution, reducing waste and the need for extensive recycling processes.
