On This Day In Chemistry

August 3rd

German chemist Johann Dobereiner discovered the role of platinum (Pt) as a catalyst on this day in 1823

He realised that a platinum (Pt) sponge could cause the ignition of hydrogen (H) at room temperature by lowering the activation energy. This effect was the precursor to the theory of catalysis, and in 1835 the term “catalyst” was coined by Swedish chemist Jacob Berzelius.
