A device for producing black phosphorus which includes a reactor having one end connected to a feeding pipe and another end connected to a discharge pipe; a propeller blade unit including a rotating shaft mounted between the two ends of the reactor and a blade element mounted on the rotating shaft; a motor connected to the rotating shaft for controlling a rotation speed of the blade element; a heating device enclosing the reactor at an outer side and defines the reactor into a plurality of heating zones; and an inert gas input connected to the discharge pipe. The device is simple and safe in operation, can optimize the production process at low cost, and has high level of automation, thus facilitating a continuous production of black phosphorus under normal pressure.

Device and method for industrialized continuous production of black phosphorus

A method of producing black phosphorus which includes the steps of: weighing and mixing reaction raw materials which comprises metallic tin, red phosphorus and monocrystalline iodine, wherein a weight ratio of tin: red phosphorus: iodine is 0.6-3.5: 5-45: 0.1-0.8; feeding the mixture to a high-temperature resistant metal reaction tube; removing air by introducing inert gas and sealing the reaction tube tightly; placing the metal reaction tube inside a muffle furnace for carrying out calcination reaction by first increasing a temperature at a preset rate to a maximum temperature and keeping warm and then decreasing a temperature at a preset rate and keeping warm, then to room temperature so that the black phosphorus is produced. The conversion rate is very high and the quality of the produced product is classified as high quality.

Method for producing black phosphorus

A group of Hyperthermia micro/nano particles are prepared. Each nanoparticle has a first diameter between 1 micron to 50 micron and a first thickness between 100 nm to 5 micron, in a disk-like shape. The hyperthermia micro/nano particles in the present show enhanced heat properties under microwave radiation which can be used for diagnosis and therapeutic purpose in cancer treatment.

Lithographically defined nanoparticles for microwave absorption

In various embodiments, the invention teaches a method for water splitting with much higher efficiency than previous methods. By decreasing the distance between two electrodes to nanometer scale, even shorter than the electric field screening length, the external power required for water splitting is significantly reduced.
