Catalysis

One example per milestone in the history of catalysis: Doebereiner’s platinum and Berzelius’s naming of catalysis, Arrhenius and Ostwald’s kinetic definition of a catalyst, Sabatier’s catalytic hydrogenation, Constable’s compensation effect, Balandin’s volcano curve, and Boudart’s turnover frequency.
