Surface chemistry dictates stability and oxidation state of supported single metal catalyst atoms

“…This nding goes against the common reductionistic approach of using a single RDS across a volcano plot 6,7 and underscores the complexity of catalytic reactions, especially those involving oxygen. Although catalyst screening with several competing steps and intermediates has been reported for reactions occurring over unsupported metal surfaces 37,38 and homogeneous catalysts, [39][40][41][42][43] approaches for supported SACs are missing. In the present study, this change of RDS and catalyst resting state with varying metal oxophilicity is reected in the analytical rate expressions that apply to the Pd-and Fe-like SACs.…”

Spatial-confinement induced electroreduction of CO and CO2 to diols on densely-arrayed Cu nanopyramids

“…The binding energies of reaction intermediates on catalysts are dependent on each other, as is decided by scaling relationships. 42,43 This is because adsorptions of different intermediates with the same pattern, e.g. C containing intermediates are correlated.…”

Standardized Stirring for Small Scale Surveys

“…Catalytic reactions are sensitive to a wide range of experimental conditions, even in homogeneous systems. [1][2][3][4][5][6][7][8][9] These conditions include variables, such as concentration of reactants and catalyst, [10] stirring rate, [11] reaction time and temperature, [12] which contribute to the outcome of a catalytic system after optimization. This study focuses on the influence of stirring in a small-scale crosscoupling reaction.…”
