PREPARATION OF NANO-IRON/CARBON MATERIAL FROM NAPHTHALENE AND FERROCENE

A novel material of iron nanoparticles carbon was prepared from the mixture of ferrocene and naphthalene by heat treatment at 420 ℃ for 2 h~6 h under auto pressure. The diameter of the resulting iron particles dispersed in the carbon matrix is about 20 nm~50 nm. The size and distribution of the iron particles have certain connection with reaction time in the scope of 2 h~6 h, and with the elongation of soaking time, the diameter tends to become larger. In this reaction, naphthalene pyrolyses into a pitch by the catalysis of ferrocene and at the same time ferrocene is reduced to α Fe dispersed in carbon uniformly. The material of nano iron particles dispersed in carbon shows the soft magnetic properties measured by vibrating sample magnetometer and can be used as magnetic recorder materials.
