Pulse input offers several advantages: 1. High Sensitivity: The technique is sensitive to small changes in reactant and product concentrations, making it ideal for detailed studies. 2. Non-Steady-State Conditions: Unlike steady-state methods, pulse input captures the transient behavior of catalysts, providing a more comprehensive understanding. 3. Minimal Catalyst Degradation: The small amount of reactant used reduces the risk of catalyst poisoning or deactivation. 4. Versatility: Pulse input can be applied to a wide range of catalytic systems and reactions, from gas-phase to liquid-phase processes.
