nanostructures

The effectiveness of the galvanic replacement method for decorating a porous surface with metal nanoparticles and nanostructures is considered. It is shown that depending on the functional purpose, foam, porous, and dendritic metal 3D substrates are mainly used for modification by galvanic replacement. In particular, these are nickel and copper substrates on which noble metals are deposited. The peculiarities of the formation of nanosized deposits on porous copper and nickel surfaces depending on the structure of the latter and the conditions of galvanic substitution are given.

The methods of nanostructures adjustment in cross-linked epoxy polymers were considered. The large potential of changing mechanical properties of these materials by nanoclusters relative fraction variation was shown.

The role of intra- and intermolecular H-bonds in mechanisms of catalysis with triple heterobinuclear hetero ligand complexes NiII(acac)2∙NaSt(LiSt)∙PhOH, including nickel and redox-inactive metal Na(Li), in the ethylbenzene oxidation by dioxygen into -phenyl ethyl hydroperoxide is discussed. The AFM method has been used for research of the stable supramolecular nanostructures formation possibility on the basis of triple complex NiII(acac)2∙NaSt∙PhOH, with the assistance of intermolecular H-bonds.
