Abstract

The invention discloses a prussian-blue derivative Cd2[Fe(CN)6] nanorod and a preparation method thereof. The preparation method for the Cd2[Fe(CN)6] nanorod comprises: firstly adding proper amount of potassium ferrocyanide, polyethylene glycol (PEG-400), a cadmium salt and deionized water into a hydrothermal reaction kettle core, putting into a baking oven and performing 120 DEG C-180 DEG C constant-temperature reaction, and naturally cooling to room temperature after the reaction is finished; and performing centrifugation washing and drying on the prepared product, so as to prepare the Cd2[Fe(CN)6] nanorod. After the prepared Cd2[Fe(CN)6] powder is tested by an X-ray diffractometer and a scanning electron microscope, Cd2[Fe(CN)6] is a nanorod, is uniform in particle size distribution, and can be used as a material used for making electrochromic devices and a secondary battery electrode material.

Description

technical field [0001] The present invention relates to the technical field of materials, in particular to a Prussian blue derivative nanorod and a preparation method thereof. Background technique [0002] Prussian blue derivatives consist of ,in k , l is an integer, , For transition metals, they may be the same element or different elements. Due to the excellent electrochemical reversibility and stability of Prussian blue and its derivatives, and the advantages of easy preparation, its application fields have developed from the initial dyes and chromogens to the current electrochromic materials, secondary battery materials, hydrogen storage, etc. materials, electrochemical catalysts, etc. [0003] At present, the preparation methods of Prussian blue derivatives mainly include electrochemical deposition method, liquid phase precipitation method, template synthesis method and microemulsion method. Among them, although the electrochemical deposition method and the li...
