Our investigation of the interaction of metal hydrides and complex metal hydrides with carbon nanostructures (C60, CNT’s, etc.) has demonstrated that these composites reversibly interact with hydrogen. Through a series of spectroscopic analysis of these materials, the active hydrogen storage material resembles a metal-doped hydrogenated fullerene. Owing to our ability to judiciously control the metal doping and hydrogen content of these materials, we can fine-tune the properties of the materials for new applications. This led to the remarkable enhancement in lithium ion conduction in LiBH4-C60 nanocomposites observed at room temperature. Experimental and theoretical work suggested a nanoionic mechanism is responsible for the enhanced ionic conduction due to the destabilization/breaking of the Li+/BH4- ion pair by C60. The photophysical properties of these carbon nanocomposites have also been investigated. The hydrogen content of these materials can be used fine-tune the emissive properties of the material with potential applications in luminescence down-shifting devices.
