Several significant milestones have marked the history of catalysis:
1831: Humphry Davy discovered the catalytic properties of platinum in the oxidation of alcohol. 1909:Fritz Haber and Carl Bosch developed the Haber-Bosch process, which uses iron catalysts to synthesize ammonia from nitrogen and hydrogen. 1963: The Ziegler-Natta catalyst, developed by Karl Ziegler and Giulio Natta, revolutionized the production of polymers like polyethylene and polypropylene. 1970s: The development of catalytic converters for automobiles significantly reduced harmful emissions, making a substantial impact on environmental protection.
