Abstract
Abstract Cobalt nickel bimetallic oxides (NiCo 2 O 4 ) have received numerous attentions in terms of their controllable morphology, high temperature, corrosion resistance and strong electromagnetic wave (EMW) absorption capability. However, broadening the absorption bandwidth is still a huge challenge for NiCo 2 O 4 -based absorbers. Herein, the unique NiCo 2 O 4 @C core–shell microcubes with hollow structures were fabricated via a facile sacrificial template strategy. The concentration of oxygen vacancies and morphologies of the three-dimensional (3D) cubic hollow core–shell NiCo 2 O 4 @C framework were effectively optimized by adjusting the calcination temperature. The specially designed 3D framework…
