The term catalysis (from the Greek kata-, “down,” and lyein, “loosen”) was first employed by the great Swedish chemist Jöns Jacob Berzelius in 1835 to correlate a group of observations made by other chemists in the late 18th and early 19th centuries.

What is the difference between catalysis and uncatalyzed reactions?
Catalyzed reactions have a lower activation energy (rate-limiting free energy of activation) than the corresponding uncatalyzed reaction, resulting in a higher reaction rate at the same temperature and for the same reactant concentrations. However, the detailed mechanics of catalysis is complex.
