An integrated approach to Deacon chemistry on RuO2-based catalysts

► RuO2/SnO2 Deacon catalysts consist of two major RuO2 morphologies, (2-4 nm particles) and 1-3 ML epitaxial RuO2 films. ► Steady state Deacon kinetics indicates a medium-to-strong positive effect of reactants (HCl, O2) partial pressures. ► There is strong product inhibition by water and chlorine. ► On the extensively chlorinated surface, oxygen activation is the rate-determining step. ► DFT-based micro-kinetic modeling suggests that the reaction is structure sensitive.
