Several strategies can be employed to mitigate reduced reaction rates in catalysis:
Regeneration of Catalyst: Techniques such as calcination or chemical treatment can be used to remove poisons and regenerate the catalyst's activity. Optimization of Reaction Conditions: Adjusting temperature, pressure, and concentration of reactants can help maintain optimal reaction rates. For example, operating at moderate temperatures can prevent catalyst deactivation due to sintering. Use of Promoters: Adding small amounts of promoter substances can enhance the activity and stability of the catalyst. Promoters can help in maintaining the dispersion of active sites and preventing deactivation. Change of Catalyst: In some cases, switching to a more robust catalyst that is less prone to deactivation can be beneficial. Researchers continually explore new catalyst materials to improve performance and stability.
