Faraday Discussions, 180 (2015), S. 35 - 53.

We describe a new in operando approach for the investigation of heterogeneous
processes at solid/liquid interfaces with elemental and chemical specificity which
combines the preparation of thin liquid films using the meniscus method with standing
wave ambient pressure X-ray photoelectron spectroscopy [Nemˇs´ak et al., Nat.
Commun., 5, 5441 (2014)]. This technique provides information about the chemical
composition across liquid/solid interfaces with sub-nanometer depth resolution and
under realistic conditions of solution composition and concentration, pH, as well as
electrical bias. In this article, we discuss the basics of the technique and present the first
results of measurements on KOH/Ni interfaces.
