Abstract: In this talk, I will
present our recent progress in understanding
solid-liquid interface catalysis
[1-4]. Methodologically, we developed a periodic continuum solvation model based
on the modified-Poisson-Boltzmann equation within the periodic DFT slab
framework, which is designed for studying complex catalytic reactions at the
solid-liquid reactions under the influence of electrochemical potentials,
surface charges and solution [3,4]. Using the approach, we investigated the
metal (Au, Pt) and metal oxide (TiO2) nanoparticle equilibrium shape vs. size in
aqueous solutions and found that metal nanoparticles are distinct from the
metal-oxide nanoparticle in the size~shape relation and in the concentration of
the exposed minority facets. Our approach is also utilized to investigate
reactions on these nanoparticles in aqueous surroundings [1,2].
