Abstract

The monolayer formation of even-numbered alkyltri-methylammonium bromides CnTAB (n = 6-16) at the graphite/water interface is studied by applying frontal-flow and pulsed-flow calorimetric methods. It is concluded that surface characterization of heterogeneous catalysts by the chemisorption of suitably elected probe molecules from inert solvents is promising.
