Synthesis of two-dimensional micron-size single-crystalline Prussian blue nanosheets by hydrothermal methods assisted by glucose

Prussian blue Fe4[Fe(CN)6]3 nanosheets have been successfully prepared by a simple hydrothermal process employing the reactions between K3[Fe(CN)6] and glucose (C6H12O6). X-ray diffraction and transmission electron microscopy measurement results show that the Prussian blue nanosheets are highly crystalline with a face-centered-cubic structure of a = 10.26 Å. It was found the C6H12O6 is not only a reductant, but also may be a template for synthesizing the nanosheets.
