Facile synthesis of flower-like nickel nanocrystals and properties Original Research Article

A solvo-hydrothermal synthesis approach for the preparation of a new type of flowerlike nickel nanostructure is reported. The as-synthesized flower-like nickel nanocrystallites were characterized by X-ray diffraction and scanning electron microscopy. The nickel flowers modified glassy carbon electrode can be prepared and used to detect methanol and ethanol in the solution. The results show that the nickel flowers give a very high activity for detecting the methanol and ethanol, which provide a new application of nickel flowers. Compared with that of bulk nickel, thus-prepared nickel flowers showed a much enhanced coercivity.
