Каталізатор – грец. κατάλυσις ≈ руйнування, розпад або розчинення. Речовина, яка змінює швидкість хімічної реакції, але хімічно і кількісно залишається незмінною.

Каталізаторами є метали VIII групи (Fe, Ni, Co, Pt, Pd), срібло (Ag), оксиди (MgO, ZnO, Fe2O3, Cr2O3, WO3), різні ферменти тощо. Використовуються для виробництва аміаку, кислот, синтетичних смол, каучуку, пластмас і т.д. У автомобільній промисловості каталізаторами називають пристрої для нейтралізації вихлопних газів.

У переносному значенні слово застосовують для означення певних дій або явищ, які прискорюють різні процеси, в тому числі соціальні, політичні тощо.

Приклади:
• Ферменти – це біологічні каталізатори, ті ж таки складні білки.
• Емігранти – це мовби «каталізатор», що прискорює й прояснює хід соціальної реакції.
• Ти не зможеш урятувати світ. Врятуй своє серце. Будь каталізатором. Створюй життя там, де здатний це зробити. Бунтуй. Будь щасливим і дозволь іншим бути щасливими.
