A common assumption in chemistry is that the coordination number of a catalyst’s surface determines the reactivity of the reaction it catalyzes. Strikingly, chemists from Leiden University have now proven that this is not true for nature’s most simple chemical reaction: the dissociation of hydrogen. The researchers managed to measure the so-called absolute reactivities of this reaction, a first in science. They published their findings in Angewandte Chemie.


Secret weapon

Catalysts are widely used in our daily lives, such as the platinum catalyst in your car exhaust. However, it is often not understood how they exactly work. Professor Ludo Juurlink and his group try to change this and have a secret weapon to do so: a curved platinum surface. Last year, this piece of equipment earned them two publications in leading journals: in Science they finally proved which theoretical model for the
