Single crystal XRD characterization of FexGa1-x & GID characterization of a monolith Al₂O₃ + Pt

We are interested in solving the crystal structure of a phase observed when liquid gallium is in contact with NaOH solution. Currently, we have EDX, STEM, SAED, EDS, SEM, and EBSD data which suggests that the hexagonal crystals that form are novel and have never been reported upon in previous literature studies. We are hoping to acquire the unit cell for the synthesized FexGa1-x particles and collect full sphere data to sufficiently high resolution so we can identify the structure ex-situ. Previous attempts to collect such data on single crystal XRD instruments have been unsuccessful due to the particles small size (hexagonal with ≈ 10 µm side length) giving limited diffraction peaks with low signal to noise. In the second part we want to characterize a monolith of alumina coated with low coverage of platinum, in order to see if this materials is suited for a liquid organic hydrogen carrier (LOHC) reactor.
