Abstract:Due to its large band gap and uniquely layered crystalline structure, \chem{MoO_3} is an attractive material in the field of organic photovoltaics. \chem{MoO_3} has also been reported to exhibit photo- and electrochromic activity, and shows great promise as a catalyst, sensing material, and electrode in lithium-ion batteries. Previous studies have explored the reactivity of the \chem{Mo_xO_y} + \chem{H_2O} $\rightarrow$ Mo$_{x}$O$_{y+1}$ + \chem{H_2} reaction. This most recent study introduced Mn to the \chem{Mo_xO_y} structure in order to create a less oxophilic metal center. Photoelectron spectroscopy aided by a newly implemented planar ion funnel were utilized to probe the unique electronic properties of anionic \chem{MoMnO_y}$^{-}$ clusters reacted with \chem{H_2O}, to illuminate how this substituted element impacted the two-centered mechanism of hydrogen evolution. Of particular interest were the structures of \chem{MoMnO_4}$^{-}$ when produced by direct laser ablation and as a product of oxidation of \chem{MnMoO_3}$^{-}$ with \chem{H_2O}.
