Copper oxide nanowhiskers: structure, growth mechanisms, and associated stresses

Abstract

Abstract A detailed study of the structure of nanowhiskers and the processes accompanying their growth during thermal oxidation are presented. The structure of nanowhiskers is studied by scanning and transmission electron microscopy and X-ray diffraction. The role of internal stresses in the substrate on the growth of nanowhiskers is shown, and the stress state for various configurations of the copper/copper oxide system is calculated. The sorption, catalytic, electrochemical, and mechanical properties of oxide nanowhiskers are described. The areas of the practical application of copper oxide nanowhiskers such as water purification systems and lithium batteries are shown.
