a, b Bader charge analysis for p-RuO2 (a) and Mn0.2RuO2 (b). c Differential charge density analysis of adsorption *OH on Ru atom (left) and Mn (right) atom for Mn0.2RuO2. d Gibbs free energy diagram for AEM path and OPM path on the surface of Mn0.2RuO2. e PDOS and d-band center of Ru 4d (−4.23) for p-RuO2, Ru 4d (−4.32) and Mn 3d (−4.61) for Mn0.2RuO2. Corresponding d-band centers are denoted by arrows. f Calculated energy for Ru demetallation of p-RuO2 and Mn0.2RuO2.
