Overview of Cobalt Phosphide Co2P Powder

Cobalt phosphide is a gray spiculate. Its relative density (15℃) is 6.14. The melting point is 1386 ℃. Cobalt phosphide is soluble in nitric acid, aqua regia but insoluble in water. Cobalt phosphide (CO2P) is an intercalation compound formed by a phosphorus source entering the transition metal cobalt lattice. Cobalt phosphide can be used in magnetism, lithium battery anode materials, hydrogenation catalysis and photocatalytic degradation, etc. Cobalt phosphide is a kind of semiconductor material with low bandgap, high thermal stability, chemical stability, strong electrical conductivity and efficient catalytic performance, extremely meet the requirements of the preparation of an efficient water decomposition catalyst, which is a kind of efficient, stable and cheap transition metal phosphide. 

Product Performance of Cobalt Phosphide Co2P Powder

Cobalt phosphide is a compound with an antispinel structure composed of Co and P. It is a mixture of the elements Co and P. The chemical formula is Co2P. Its chemical formula is Co2P, and its molecular weight is 121.73. Cobalt phosphide is a solid, black powder at room temperature, insoluble in water and not easily oxidized by air. It can be stabilized in air and its melting point is 247℃. Cobalt phosphide has good electrical conductivity and magnetic properties. At room temperature, it has a conductivity of about 10^6S/m and is ferromagnetic. The resistivity of this material decreases as the temperature increases, and at temperatures up to about 100 K, it has a resistivity of 0.02 Ω-m.

Technical Parameter of Cobalt Phosphide Co2P Powder

How is Cobalt Phosphide Co2P Powder Produced?
There are four ways to prepare cobalt phosphide according to the phosphorus source. In the first, trityl phosphorus (TOP) is used as a phosphorus source to synthesize phosphates, which can be obtained in organic mixtures by thermal decomposition of metal phosphates, which is the oil bath method. When tri octyl phosphorus is used as the phosphorus source in the Ullmann reaction, it is easy to cause the agglomeration of the generated cobalt phosphate nanowires. Second, the application of hydrogen reduction of metal phosphates, due to phosphorus and oxygen bond energy is stronger, if you want to destroy the keys, phosphorus and oxygen metal and the formation of phosphorus key only occur under high temperature, however, this process is easy to form the metal particles, and the formation of metal particles has greatly enhanced the adsorption of hydrogen, metal overflow phosphate at the same time, led to the reduction of phosphate to the phosphide. However, due to the high sintering temperature, the synthesis of phosphates by phosphate usually results in the formation of large grains for the most part. Third, the application of a relatively mild and simple hypophosphite route, that is, through high-temperature decomposition (300-400℃) heating decomposition of sodium hypophosphite, in situ generations of toxic PH3 will reduce the metal source. Fourthly, the metal phosphide was prepared by using element phosphorus under hydrothermal conditions (140-200℃). The element phosphorus had white phosphorus, yellow phosphorus and red phosphorus as phosphorus sources, which may cause the agglomeration of the prepared cobalt phosphide and thus could not control the size and composition of the particles.
