High energy neutron powder diffraction on graphene and metal-decorated graphene
Graphene is a very promising material and appears particularly suitable for developing efficient hydrogen storage systems, if it is “decorated” with proper metal ions. Recently, we managed to produce gram-scale bulk defective graphene by chemical methods and to decorate it with Lithium and Nickel atoms. Although a structural characterization of chemically synthesized graphene is missing, the investigation of the defects as well as of the decorating metal local environment is a fundamental prerequisite in order to develop an efficient graphene-based gas storage device. Hence we propose to investigate the morphology of these systems at the nanoscale, by means of high energy neutron diffraction and atomic pair distribution function (PDF) data analysis using the D4 diffractometer at the ILL.
