Objective
The overall objective of the joint project is to use concept of composite material consisting of porous matrix and hydride forming metal nanofragments randomly distributed in this matrix for creation of effective material for hydrogen generation from water and/or for hydrogen storage. The program proposed is based on a new approach to hydrogen storage material synthesis. It summarizes three fruitful concepts usually used separately, i.e. creation of nanosized metal powder in order to improve kinetic parameters of hydrogen uptake and release; modification of metal lattice by interstitial atoms in order to decrease the temperature of metal - hydrogen interaction through change in thermodynamic parameters of hydrogen uptake and release; protection of active metal/metal hydride nanofragments from atmosphere impact in order to store the high reactive material. In the frame of the project, new fundamental knowledge on poorly studied triple metal/matrix - hydrogen systems (structure, kinetics, and thermodynamics) will be obtained and published. The results of this fundamental study are expected to be the synthesis nanocomposite - effective hydrogen storage material, which can be used in compact, light, safe and affordable containments. The specific objectives include: 1. The mechanochemical synthesis of nanocomposites by a self-developed mechanochemical technique in a reactor in vacuum or in the presence of different gases (Ar, He, H2, CO); the investigation of optimal regime and energy input necessary for successful material synthesis; the control on the process of nanocomposite formation including the effect of matrix material (graphite, BN (B2O3), material prepared from rice husks) and metal-to-matrix ratio. Effect of gas atmosphere and the effect of average energy intensity introduced into the material will be controlled in detail by a variety of experimental techniques: (1) in situ kinetic measurements to monito the gas evolution and consumption; (2) X-ray diffraction to test the powder composition on different steps of preparation; (3) Spectroscopic methods to test the surface and bulk changes in different stages of synthesis; (3) temperature-programmed reaction and -desorption measurements, to test the nature and stability of local occupation sites available for hydrogen and to determine the energetics related to hydride formation and decomposition; (4) scanning and high-resolution transmission electron microscopy for microstructural investigations; (5) synchrotron excited X-ray emission and absorption to study the local atomic and electronic structure; (6) positron annihilation to study the nature and density of responsible hydrogen trapping sites and to characterize the porosity of the matrix. Model electronic structure calculations simulating the occupation of different interstitials of metal host lattice by hydrogen and additives will be carried out in order to understand the effect of modification on hydrogen state in metal - matrix system.
