Embodiment 1

[0013] Pipette 20mL 1mmol / L FeCl respectively 3 and 1mmol / L K 3 [Fe(CN) 6 ] Pour the two precursor solutions into a beaker, drop an appropriate amount of hydrochloric acid with a dropper to adjust the pH value of the mixed solution to 1-2, put the magnetron into the solution, and continuously stir the reaction on the magnetic stirring device for 24 hours, then put the reaction The micronano Prussian blue particles can be prepared by placing them in liquid solution, centrifuging and washing, and then drying them in an oven at 90°C.

Embodiment 2

[0015] The preparation method of this example is the same as that of Example 1, and the reaction time is controlled to be 48 hours. Under the condition that other conditions remain unchanged, micronano Prussian blue particles are also synthesized.

[0016] The characterization of the micronano Prussian blue particles synthesized according to the method of the present invention is shown in the appendix figure 1 shown

Abstract

The invention relates to a preparation method of novel micro-nano prussian blue particles, in particular to micro-nano prussian blue particles which are synthesized by mixing two precursor solutions, i. e. potassium ferricyanide and ferric trichloride of prussian blue, and then fully stirring the mixture under the condition of a proper pH value. A synthesis device adopted by the method is simple; a common beaker is taken as a reaction vessel, and a magnetic stirring apparatus having a stirring function is used. According to the synthesis technology, the micro-nano prussian blue particles are synthesized by controlling the conversion speed of the prussian blue in a solution. The micro-nano material can be used for the application fields such as solid state batteries, electrochromic devices, molecular magnets, and the like.

Description

technical field [0001] The present invention relates to a preparation method of a novel micro-nano Prussian blue particle, in particular to a method for synthesizing micro-nano-level particles by mechanically stirring two precursors of Prussian blue as reactants and adjusting the solution to an appropriate pH value. The Prussian blue particles belong to the field of synthetic chemistry of materials. Background technique [0002] Prussian blue and its analogues are a class of polynuclear transition metal ferricyanides with an open structure similar to zeolites. Due to the H 2 o 2 and O 2 The reduction process exhibits excellent catalytic activity and selectivity, is considered as an artificial catalase, and is widely used in the construction of biosensors. In addition, due to its fast charge transfer and magnetic change properties, it also has potential applications in the fields of molecular magnet devices, electrochromic displays, energy storage, and batteries. The usu...
