While selecting an appropriate reaction medium can enhance catalytic efficiency, several challenges may arise:
Solvent Waste: The disposal of solvents, especially organic ones, can pose environmental and economic challenges. Medium-Induced Catalyst Deactivation: Some media can lead to catalyst deactivation over time, requiring frequent catalyst regeneration or replacement. Complexity in Medium Optimization: Finding the optimal medium for a specific reaction can be time-consuming and may require extensive experimentation.
