WebCatalyst is a term derived from Greek καταλύειν, meaning “to annul,” or “to unite,” or “to pick up.”. Meanwhile, the concept of catalysis was first researched by chemist Elizabeth Fulhame and it was described in her book in the year 1794. This book content was based on her work in oxidation-reduction experiments. WebCatalysis (/ k ə ˈ t æ l ə s ɪ s /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈ k æ t əl ɪ s t /).Catalysts are not consumed in the reaction and remain unchanged after it.
