Crystal structure: Its crystal structure is more complex, for the selenide of divalent nickel, there are a variety of phase states and structural types, which also makes its physical and chemical properties have a certain diversity.

Preparation method:

Solid phase reaction method: nickel source (such as nickel powder, nickel oxide, etc.) and selenium source (such as selenium powder, hydrogen selenide, etc.) are mixed in a certain proportion, and solid phase reaction is carried out at high temperature to prepare NiSe powder.

Chemical vapor deposition method: using organic compounds of nickel and selenium compounds in the gas phase under the condition of biochemical reaction, deposited nickel selenide film or powder on the substrate.

Solvothermal method: nano-sized nickel selenide powder can be prepared by the reaction of nickel salt and selenium source in organic solvent under high temperature and high pressure.

Application field:

Catalytic field: Due to its unique chemical properties, NiSe powder can be used as a catalyst in a variety of chemical reactions, such as hydrogenation reaction, dehydrogenation reaction, water decomposition reaction, etc.

Energy storage field: In energy storage devices such as batteries and supercapacitors, NiSe powder can be used as an electrode material to improve the performance of energy storage devices by using its good electrochemical properties.

Photoelectric field: Because of its semiconductor properties, it can be used to prepare photoelectric devices such as photodetectors and solar cells.

Sensor field: NiSe powder is sensitive to certain gases and chemicals, and can be used to prepare gas sensors and chemical sensors to detect harmful gases or chemicals in the environment.
