Gas-phase activation of holmium tetranitrato complexes likely leads to formation of hydroxylated species through the loss of nitric acid, not water splitting

Abstract: It has been observed that water can react with activated gas-phase lanthanide tetranitrato complexes ([Ln(NO3)4]-) to form a hydroxylated species. These reactions, which are proposed to involve water splitting, are observed for most -- but not all -- of the lanthanides. Thus, study of this system could yield insight into how small changes in electronic structure (through variation of the lanthanide species) influences water-splitting reactions, help guide development of new materials used to convert water to hydrogen using electricity. The mechanism proposed in the literature is: (Step 1) [Ln(NO3)4]- ? [LnO(NO3)3]- + ?NO2 (Step 2) [LnO(NO3)3]- + H2O ? [LnOH(NO3)3]- + ?OH The purpose of this study is to determine if the reaction mechanism really does involve splitting of water or proceeds through an alternative pathway.
