Hydrogen in metallic nanomaterials

Problems concerning the synthesis of hydrogen-containing nanomaterials based on metals, alloys and intermetallics are considered. Characteristics of hydrogen absorption by and hydrogen desorption from these materials are analyzed. Specific features of the phase diagrams of metal–hydrogen systems in the case of nanostructured components are discussed. Data on the structure and defects, electronic structure and physicochemical properties of nanocrystalline metal hydrides are generalized; poorly studied problems in this field of research are outlined. The bibliography includes 99 references.
