Embodiment 1
[0034] A fiber-phase red phosphorus nanoparticle, specifically prepared through the following steps:
[0035] (1) Synthesis of zinc oxide nanoparticles: 1.885 g of zinc nitrate hexahydrate, 2.185 g of sodium dodecylbenzenesulfonate and 6 g of sodium hydroxide were weighed and dissolved in 60 mL of ethanol with a balance. The solution is sonicated until the solute is uniformly dispersed in the solution. Put the sonicated solution into a 100mL reactor, put the reactor in a muffle furnace at 100°C, and react at high temperature for 9h. The reacted solution was centrifuged (9000r / min, 10min) to collect zinc oxide nanoparticles. Then centrifuged 3 times with absolute ethanol, and then centrifuged 3 times with deionized water. The precipitate after centrifugation was vacuum-dried in a vacuum oven at 60°C.
[0036] (2) Preparation of amorphous pure red phosphorus: Weigh 5.9 g of commercial amorphous red phosphorus and add it to 60 mL of deionized water, transfer the solution to a ...
Embodiment 2
[0050] A fiber-phase red phosphorus nanoparticle, specifically prepared through the following steps:
[0051] (1) Synthesis of zinc oxide nanoparticles: 1.885 g of zinc nitrate hexahydrate, 2.185 g of sodium dodecylbenzenesulfonate and 4.8 g of sodium hydroxide were weighed and dissolved in 60 mL of ethanol with a balance. The solution is sonicated until the solute is uniformly dispersed in the solution. Put the sonicated solution into a 100 mL reaction kettle, put the reaction kettle in a muffle furnace at 90°C, and react at high temperature for 11 hours. The reacted solution was centrifuged (9000r / min, 10 min) to collect zinc oxide nanoparticles. Then centrifuged 3 times with absolute ethanol, and then centrifuged 3 times with deionized water. The precipitate after centrifugation was vacuum-dried in a vacuum oven at 50°C.
[0052] Steps (2) (3) (4) are consistent with embodiment 1.
[0053] Scanning electron microscopy was carried out to the fiber-phase red phosphorus na...
Embodiment 3
[0055] A fiber-phase red phosphorus nanoparticle, specifically prepared through the following steps:
[0056] (1) Synthesis of zinc oxide nanoparticles: 1.885 g of zinc nitrate hexahydrate, 2.185 g of sodium dodecylbenzenesulfonate and 6 g of sodium hydroxide were weighed and dissolved in 60 mL of ethanol with a balance. The solution is sonicated until the solute is uniformly dispersed in the solution. Put the sonicated solution into a 100mL reaction kettle, put the reaction kettle in a muffle furnace at 105°C, and react at high temperature for 10h. The reacted solution was centrifuged (9000r / min, 10min) to collect zinc oxide nanoparticles. Then centrifuged three times with absolute ethanol, and then centrifuged three times with deionized water, and the precipitate after centrifugation was vacuum-dried at 65°C.
[0057] Step (2) (3) (4) is the same as embodiment 1;
[0058] The compound of zinc oxide nanoparticles and red phosphorus prepared above was detected by scanning e...
