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.
