Structure of Molecular Hydrogen in Synthetic Laponite Clay Hydrates


In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this experiment: (i) understanding the fundamental (quantum) properties of confined molecular hydrogen, and; (ii) the search for improved hydrogen storage materials. We will study H2 in synthetic high charge Na, Ca- and Mg-laponite. Before each experiment the samples will be treated with D2O to expand the interlayer region to around 3.5 ¿ 6.0 Å, and then be baked out at between 60 to 140C to yield partially hydrated samples which we have shown readily accept H2 and D2. Sequential dosing with H2/D2 will be conducted in situ around 50K and < 2.0 bar. We are particularly interested in the local structure around the H2 including the interaction with interlayer cations and clay surfaces, and the formation of 2-D liquid H2.
