WebTraditional interpretations of the effects of promoters and poisons evoke electronic or structural effects. However, catalysis is a dynamite phenomenon: 1) molecules cyclically adsorb on the active sites, react, and desorb; 2) many species actively move on the surface; and 3) the surface structure of the catalysts gets continuously reshaped.
WebCatalyst-poison-resistant promoters protect the active phase against poisoning by impurities, either present in the starting materials or formed in side reactions. [Pg.190] One promising extension of this approach Is surface modification by additives and their Influence on reaction kinetics. Catalyst activity and stability under process ...
