Can the Presence of Inhibitors or Promoters Affect Catalysis?
Yes, inhibitors can decrease the efficiency of a catalyst by blocking active sites or altering the catalyst's structure. On the other hand, promoters can enhance catalytic activity by improving the dispersion of the active phase or by modifying the electronic properties of the catalyst. For example, in hydrogenation reactions, the presence of a promoter like rhenium can significantly enhance the performance of a platinum catalyst.
