The physical and chemical properties cobalt-phosphide
The gray color of cobalt-phosphide is needle-like. It has a relative density of 6.14 at 15°C. Its melting point is 1386degC. This is an effective, stable and affordable transition metal phosphide.
It is insoluble in water and nitric acid, while cobalt-phosphide dissolves in it. Intercalation compounds such as cobalt-phosphide (CO2P), are formed from the phosphorous source reaching the transition metal, cobalt. The uses of cobalt-phosphide include magnetism, the manufacture of lithium batteries anodes, hydrogenation, and photocatalytic destruction. Cobalt Phosphide is an semiconductor material that has low bandgaps, good thermal stability and chemical stability. It meets all requirements for preparing high efficiency water-splitting catalytic catalysts.
The purity and size parameters for cobalt-phosphide are:

How does cobalt phosphide CO2P powder get made?
For the purpose of synthesizing phosphate, Tritylphosphorus can be used as a source of phosphorus. This is possible in an organic mix by thermal degradation. It is possible to cause the formation of cobalt nanowires by using tri octylphosphorus as a source of phosphorus in the reaction.
The bond between phosphorus (and oxygen) is stronger so phosphorus formation, oxygen metal, and phosphorus bonds can only take place at high temperatures. This process also increases the adsorption rate of hydrogen. However, the metal will overflow with phosphate which causes the phosphate content to decrease to phosphide. The high temperature of sintering results in large grains most often when phosphate is synthesized via phosphate.
The hypophosphite pathway is relatively easy and mild. It involves the heating of sodium hypophosphite to a high temperature (325-400degC). This will decompose the salt hypophosphite. In situ, toxic PH3 will be generated.
Element preparation method
Phosphorus is used to make metal phosphides under hydrothermal conditions, 140 to 200 degC. As phosphorous sources, elemental phosphorus relies on white phosphorus (yellow phosphorus) and red phosphorus (red phosphorus).
