▎ 摘　　要

Knowledge of the adhesion energy between a liquid solvent and a clean solid surface allows for a straightforward estimation of the decrease in the adsorption energy of reactant molecules on that surface due to the presence of that liquid solvent relative to gas-phase adsorption energies. Such estimations in turn can be used to aid the design of liquid-phase catalysts, electrocatalysts, and chemical separations. We report here adhesion energies for 13 liquid-on-solid systems involving alkane and aromatic hydrocarbon films on clean single-crystal surfaces estimated by using temperature-programmed desorption (TPD) measurements of their low-temperature adsorption energies versus coverage up through bulklike multilayer coverages. Because TPD is the most common experimental technique for measuring adsorption energies, the method employed here opens new opportunities for many other estimates of liquid/solid adhesion energies. The adhesion energies of various n-alkanes on MgO(100), graphene (on Pt(111)), and Pt(111) show that the adhesion energy (per unit area) of n-alkanes is nearly independent of chain length. Based on the adhesion energies of hexanes, we show that the adhesion energy changes significantly on different materials, increasing in the order of MgO(100) < graphene < TiO2(110) approximate to Pt(111).
