Embodiment 1
[0019] Embodiment 1: Prepare silver micron hollow frame structure material according to the following steps
[0020] (1) At room temperature, configure AgNO with a concentration of 0.002mol / L 3 Aqueous solution; according to preset HF, FeSO 4 and AgNO 3 The molar ratio of 5:1.1:1 to AgNO 3 Add HF and FeSO to aqueous solution 4 , the stirring speed is set at 200 rpm, and the stirring is performed to obtain a clear mixed solution;
[0021] (2) The above mixed solution was placed in a water bath at a temperature of 35°C, and the reaction time was maintained for 1 h, and the resulting product was centrifuged, washed, and dried to obtain a silver micron hollow frame structure material.
Embodiment 2
[0022] Embodiment 2: Prepare silver micron hollow frame structure material according to the following steps
[0023] (1) At room temperature, configure AgNO with a concentration of 0.006 mol / L 3 Aqueous solution; according to preset HF, FeSO 4 and AgNO 3 The molar ratio of 15:1.1:1, to AgNO 3 Add HF and FeSO to aqueous solution 4 , the stirring speed is set at 200 rpm, and the stirring is performed to obtain a clear mixed solution;
[0024] (2) Put the above mixed solution in a water bath at a temperature of 50°C, and keep the reaction time for 0.75h, centrifuge, wash, and dry the resulting product to obtain a silver micron hollow frame structure material.
Embodiment 3
[0025] Embodiment 3: Prepare silver micron hollow frame structure material according to the following steps
[0026] (1) At room temperature, configure AgNO with a concentration of 0.01 mol / L 3 Aqueous solution; according to preset HF, FeSO 4 and AgNO 3 The molar ratio of 25:1.1:1, to AgNO 3 Add HF and FeSO to aqueous solution 4 , the stirring speed is set at 200 rpm, and the stirring is performed to obtain a clear mixed solution;
[0027] (2) The above mixed solution was placed in a water bath at a temperature of 65°C, and the reaction time was kept for 0.5h, and the resulting product was centrifuged, washed, and dried to obtain a silver micron hollow frame structure material.
[0028] The scanning electron microscope picture of the silver micron hollow frame structure material of embodiment 1-3 gained is as figure 1 shown.
