(a) Schematic energy profile of a two-step model considering the dissociative adsorption of reactants and associative desorption of products on a catalyst surface. (b) Schematic diagram of the variation in activity (black volcano curve) as a function of the adsorption energy of the I atom. The adsorption (red) and desorption (blue) are rate-determining processes. Adapted from Hou et al.26 Copyright © 2013 Rights Managed by Nature Publishing Group.
