Abstract
Molecular hydrogen (H 2 ) is the most abundant molecule in the Universe. Its formation involves catalytic reactions occurring on the surface of interstellar dust grains, but also involving polycyclic aromatic hydrocarbons (PAHs). Experiments and theoretical calculations have been performed to determine the processes governing the formation of H 2 on dust and involving PAHs. These studies were recently brought in a review paper (Wakelam et al. 2017), from which this contribution is based.
