When semi-local DFT is accurate for dissociative chemisorption on a transition metal surface, and when it is not
Density functional theory (DFT) with so-called semi-local exchange has been remarkable accurate for some dissociative chemisorption reactions on metals, but it has notoriously failed for others. A team of researchers from the University of California at Irvine and the Leiden Institute of Chemistry have…
