Non-adiabatic effects may substantially affect rate of reaction relevant to Haber-Bosch catalysis
Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…
