  报告摘要: 

  Advances in theory and methods of quantum mechanics and in supercomputers are making it practical to consider first principles (de novo) predictions of the mechanisms of complex catalytic reactions.   

  We will highlight some recent advances in such methodologies including: 

    Quantum mechanics methods for accurate nonempirical intermolecular interactions (XYGJ-OS) 

    New methods of continuum solvation for electrochemical reactions (CANDLE) 

    Grand canonical QM calculations of electrochemical catalysis at constant potential (instead of constant numbers of electrons) 

    QM metadynamics calculations of free energies of electrocatalysis at operational temperature and potential 

  which we will illustrate with recent applications to catalytic systems selected from:  

    The reaction mechanism for the electrocatalytic oxygen reduction reaction on Pt(111) and Pt alloys 

    Critical potentials for CO2 reduction on (100) and (111) Cu surfaces to form hydrocarbon fuels at various pH (0 to 14) 

    The hydrogen evolution reaction (HER) on MoS2 electrocatalysts  

    The reaction mechanism for the oxygen evolution reaction (OER) on IrO2 electrocatalysts  

    The reaction mechanism for the selective catalysis of butane to maleic anhydride on vanadium pyrophosphate heterogeneous cataktsts 

    The reaction mechanism for the selective oxidation of propane to acrylonitrile on Mo/V/Nb/TeOx heterogeneous catalysts
