Facile synthesis and optical properties of Prussian Blue microcubes and hollow Fe2O3 microboxes

In this paper, we report a novel strategy for the synthesis of Prussian Blue microcubes via hydrothermal conditions by using K3[Fe(CN)6] and glucose for the first time, and then hollow Fe2O3 microboxes have been successfully fabricated by calcination from a Prussian Blue microcube precursors. The phase structures and morphologies were studied using X-ray powder diffraction (XRD), scanning electronic microscopy (SEM), X-ray photoelectron...
