Abstract

Permeable metallic nickel and ceramic nickel-oxide materials with nanostructured surface and multilevel hierarchical porosity were created by cyclic redox post-treatment of biporous nickel (II) consolidated in the sintering-dissolution process. Additional levels of intraparticle porosity – Kirkendall pores and shrinkage nanopores – were formed during the stages of high-temperature oxidation in air and reduction in hydrogen, respectively.
