  "term": "Self-poisoning",
  "field": "Chemistry",
  "definition": "The deactivation of a catalyst by one of the products of the reaction it catalyzes, or by a reactant that undergoes a side reaction to form an inhibiting species. This process reduces the catalyst's activity over time. An example is the deposition of carbonaceous residues on a catalyst surface during hydrocarbon reactions.",
