Aqueous interfaces are ubiquitous in technological applications and in the environment and govern nu-merous important phenomena, including corrosion, photoelectrochemical splitting of water, weathering of rocks, cloud droplet nucleation, the concentration of trace gases in polar regions, and thundercloud elec-trification. Ambient pressure X-ray photoelectron spectroscopy is an excellent method to probe the heter-ogeneous chemistry of these interfaces and has been applied to a number of different systems, including ultrathin water films on metals and oxides, bulk liquid/solid interfaces, the surface of aqueous solutions in the presence of the equilibrium vapour pressure as well as trace gases, and the surface of ice, which at temperatures close to the melting point is covered by a thin liquid-like layer. In this talk I will review the progress that has been made in the area of APXPS experiments on aqueous systems and provide an out-look on opportunities for future research in this field.
