Solid State 11B-NMR Analysis of the Decomposition Products of Ammonia-borane Thermolysis in Ionic Liquids for Hydrogen Storage: Part 3-2
EMSL Project ID
39733
Abstract
We propose to investigate the decomposition products of the thermolysis of ammonia-borane in ionic liquids by solid state 11B-NMR. Ammonia-borane/ionic liquid mixtures have previously been shown to release significant amounts of hydrogen under mild conditions. We have improved upon out initial reports in various ways, e.g., altering the reaction conditions or ionic liquid used, and by the addition of catalysts. Ammonia-borane appears to decompose through a different reaction pathway in ionic liquid compared to other mediums. However, it is difficult to investigate this pathway by more traditional techniques due to the insolubility of the amineborane reaction residues. Therefore, solid state 11B-NMR experiments must be run at a sufficiently high field where the secondary quadrapole coupling is removed.Therefore, we're requesting use of EMSL's resources to complete a series of solid-state NMR data to make some final conclusions related to a publication underway with one of my students who will graduate in April and begin a new job on June 7th. Normally, we'd complete these data sets using our laboratory's NMR, but it is currently out for repair until the end of May.
