Embodiment 1
[0022] The first step, prepare 0.1M silver nitrate solution (A) and 0.1M ammoniacal liquor (B) the concentration of disodium hydrogen phosphate is 0.15M (C).
[0023] In the second step, take 10 mL of liquid A, add 22 mL of liquid B, and then add liquid C (27 mL) to keep the ratio of silver nitrate and disodium hydrogen phosphate at 1:4, age for 10 min, separate and wash, and the prepared silver phosphate Dry at 60°C for 24h. The prepared silver phosphate was dried at 60°C. Take a small amount of sample and dip it on the conductive glue, spray gold to observe the shape, use a field emission scanning electron microscope (Philips, XL-30E, SEM), set the scanning voltage to 3KV, and the magnification to 20,000 times ( figure 1 ) conditions, it can be seen that the prepared silver phosphate forms a smooth cube.
Embodiment 2
[0025] In the first step, sodium dodecyl sulfate (SDS) and disodium hydrogen phosphate are dissolved in water to prepare a solution (A) with a certain concentration, wherein the concentration of sodium dodecyl sulfate (SDS) is 0.01M, hydrogen phosphate The concentration of disodium is 0.15M; prepare 0.1M silver nitrate solution (B) and 0.1M ammonia water (C).
[0026] Second step, get B liquid 10mL, add C liquid 22mL to it dropwise, obtain the silver ammonia complex ionic liquid of clarification, as reaction precursor liquid, add A liquid (27mL) to precursor liquid according to certain rate, keep silver nitrate and The molar ratio of disodium hydrogen phosphate is 1:4. Aging for 10 minutes, separated and washed, and dried for 24 hours.
[0027] (1) By a field emission scanning electron microscope (Philips company, XL-30E, SEM), the scanning voltage is set to 3KV, and the magnification is 20,000 times ( figure 2 ) conditions, it can be seen that the prepared Ag 3 PO 4 A cu...
Embodiment 3
[0030] In the first step, sodium dodecyl sulfate (SDS) and disodium hydrogen phosphate are dissolved in water to prepare a solution (A) with a certain concentration, wherein the concentration of sodium dodecyl sulfate (SDS) is 0.08M, hydrogen phosphate The concentration of disodium is 0.15M; prepare 0.1M silver nitrate solution (B) and 0.1M ammonia water (C).
[0031] Second step, get B liquid 10mL, add C liquid 22mL to it dropwise, obtain the silver ammonia complex ionic liquid of clarification, as reaction precursor liquid, add A liquid (27mL) to precursor liquid according to certain rate, keep silver nitrate and The molar ratio of disodium hydrogen phosphate is 1:4. Aging for 10 minutes, separated and washed, and dried for 24 hours. By a field emission scanning electron microscope (Philips, XL-30E, SEM), the scanning voltage was set to 3KV, and the magnification was 10,000 times ( Figure 4 ) conditions, it can be seen that the cubic Ag with long nanorods on the non-unifo...
