Hollow Prussian blue nanoparticles are calcined under various reaction conditions to prepare nanoporous Fe oxides with a crystallized α-Fe2O3 (hematite) phase. The morphologies, surface areas, and degrees of crystallinity of the samples are varied by changing the number of hours of calcination. After calcination at 400 °C for 4 h, formation of a crystallized α-Fe2O3 phase is confirmed.
