Facile synthesis of air-stable nano/submicro dendritic copper structures and their anti-oxidation properties

Abstract

We report the facile fabrication of dendritic copper nano/submicro structures by chemical dealloying a Cu–Mn–O alloy, which breaks through the traditional thinking that complex structures cannot be obtained by simple chemical dealloying except for porous structures. The dendritic copper structures exhibit excellent air-stability at room temperature and possess high anti-oxidation properties.
