4.0 Conclusions. The dynamic catalytic promotion of A-to-B surface reactions permits order-ofmagnitude rate enhancement and control of extent of conversion for a broad set of surface mechanisms. Classification of surface mechanisms and their associated kinetic behavior requires detailed description of the key parameters defined here as gamma (γ, the ratio of variation in surface adsorbate binding energy) and delta (δ, the surface adsorbate binding energy common to two intermediates). High gamma catalytic systems (γ > 1) achieve surface resonance between an oscillating external stimulus and an oscillating surface reaction by selecting a catalyst and dynamic conditions that maintain two oscillating states of A* and B*, respectively. Alternatively, low gamma catalytic systems (γ < 1) require one of the two oscillating states to consist of a completely bare surface (open sites only). The two different dynamic catalytic behaviors are visually apparent in their Sabatier volcano shapes; superposition of numerous Sabatier volcanoes with varying γ comprise a 'supervolcano' where the regime of surfacereaction rate control is visible as deviation from the superVolcano border. Dynamic catalysis was also show to serve as a 'catalytic molecular pump' by altering the binding energy of surface adsorbate species via external work. The extent of work converted into catalytic conversion deviating from equilibrium was defined as the dynamic catalytic efficiency. For both low and high γ catalytic systems, conditions of efficient catalytic promotion as high as 30-40% were identified as a strong function of the selected dynamic oscillation conditions of frequency, amplitude, and waveform type.
