Submitted by admin on Tue, 09/03/2019 - 01:59

Nano Copper Oxide (CUO) introduction:


Nano Copper oxide appear as a brownish-black powder. They can be reduced to metallic copper when exposed to hydrogen or carbon monoxide under high temperature. Insoluble in water. dissolve slowly in alcohol or ammonia solution. Soluble in dilute acids, NH4Cl, (NH4) 2CO3, potassium cyanide solution. They are graded harmful to the environment with adverse effect on aquatic life.

Iron(III) oxide, also named for ferric oxide, is the inorganic compound with the formula Fe2O3. When the size of the Fe2O3 Iron(III) oxide is small to nanometer(1~100nm), the surface atomic number, specific surface area and surface energy of the iron oxide particles increase sharply with the decrease of the particle size, which shows the features of small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect.
