Metal-support boundary sites in catalysis - ScienceDirect

    https://www.sciencedirect.com/science/article/pii/S0926860X97002433
    The number of metal-support boundary sites in relation to total metal surface sites increases with increasing metal dispersion and, consequently, some of the phase-boundary sensitive reactions as the MCP hydrogenolysis on platinum exhibit a particle size effect.Cited by: 219

    In highly-dispersed metal catalysts, the supporting oxide stabilises the metal particles, but may also promote individual reaction steps. In particular, many reactions are believed to proceed, preferentially or exclusively, at the metal-oxide interface which contains sites with distances between metal atoms and support in the range of atomic dimensions.Cited by: 219

The reaction takes place at the perimeter of the metal and the support and therefore the boundary population is the key property determining the reactivity of systems having dual reaction sites. Furthermore, the spillover of reactive species either on the ...Cited by: 74

Adsorption Energy Correlations at the Metal–Support Boundary

    http://pubs.acs.org/doi/abs/10.1021/acscatal.7b00979
    The emergence of supercell density functional theory (DFT) over the past few decades has enabled great progress in rational catalyst design for extended surfaces of transition metals. However, insights from such metal-only models may not translate directly to metal nanoparticles dispersed on high surface area supporting phases, where metal and support may both participate in catalysis.Cited by: 12
