Abstract

A recent Letter in this Journal (Gladich et al. J. Phys. Chem. Lett. 13, 2994–3001) reported that photoelectron spectroscopy could not detect any products on the surface of aqueous Fe²⁺ jets dosed with gaseous hydrogen peroxide. The Letter however concluded that Fe(aq)²⁺ ions react with H₂O₂(g) at the water–vapor interface to produce the same Fe³⁺ + HO• products as their reaction with H₂O₂(aq) in bulk water. We argue that this conclusion is untenable because nothing can be asserted about undetected species.
