[0066] The present invention provides a method for preparing iron vanadate@polyaniline nanobelt core-shell structure material of in-situ growth polyaniline array, comprising the following steps:
[0067] 1) Under ice-water bath conditions, FeVO 4 The nanobelt is placed in a dilute acid solution to obtain solution A;
[0068] 2) dissolving the initiator in the dilute acid solution to obtain solution B;
[0069] 3) ice-water bath, under stirring, add aniline and solution B into solution A in sequence, and react to obtain iron vanadate@polyaniline nanobelt core-shell structure material with in-situ growth of polyaniline array.
[0070] FeVO described in step 1) 4 The preparation method of the nanobelt is as follows:
[0071] 1-1) Disperse iron salt and metavanadate in water to form a mixed solution;
[0072] 1-2) Adjust the pH of the mixed solution prepared in step 1-1) to 4-5, and then perform a hydrothermal reaction to obtain FeVO 4 nanoribbons.
[0073] The iron salt des...

[0155] A core-shell structure FeVO 4 @The preparation method of polyaniline nanobelt includes the following steps:
[0156] 1) Preparation of dilute hydrochloric acid solution:
[0157] Take a certain amount of 12mol / L concentrated hydrochloric acid with a pipette and dissolve it in 500 mL of water to prepare a dilute hydrochloric acid solution with a pH of 5;
[0158] 2) FeVO 4 Preparation of nanobelts: Weigh 0.5406g FeCl 3 ·6H 2 O, 0.2340g NH 4 VO 3 and 80mL H 2 O in a beaker, stir magnetically at room temperature for 25min, stirring speed is 500rpm, make it completely dissolved, suck the diluted hydrochloric acid solution prepared in step 1) with a dropper, under magnetic stirring, dropwise add it into the beaker, use a glass Dip the stick into the liquid in the beaker, observe the precision pH test paper on the drip plate, it turns light red, and the pH value is 4.2, stop dripping dilute hydrochloric acid. The liquid was transferred to the inner tank of the polytet...
