surface poisoning

What are the Effects of Surface Poisoning?

The primary effect of surface poisoning is the decreased activity of the catalyst. As the active sites become occupied by poisons, fewer sites are available for the catalytic reaction, leading to a lower reaction rate. In severe cases, the catalyst may become completely inactive. Additionally, surface poisoning can affect the selectivity and stability of the catalyst, altering the desired product distribution and potentially causing the catalyst to degrade faster.
