And Chemical Properties

This paper contains an account of the results of the continuation of the experiments on the action of light on the liquid iron carbonyl (iron penta-carbonyl) and the action of heat on the resulting solid compound, diferro-nonacarbonyl, Fe 2 (CO) 9 , which were described in a paper on “The Physical and Chemical Properties of Iron Carbonyl,” communicated to the Society in 1905. The experiments on the action of light on iron pentacarbonyl under varied conditions have resulted in new and interesting observations, and approximate measurements of the velocity of the reaction induced by light have been made and compared with that of other reactions induced by light.

ABSTRACTIn this paper we are proposing the synthesis of iron and cobalt nanoalloys via the codecomposition of iron and cobalt carbonyl precursors in the presence of polystyrene as the surface stabilizing agent. In order to form iron-cobalt nanoalloys with no preferential aggregation of metal atoms resulting in phase segregation, the decomposition kinetics of the iron pentacarbonyl and dicobalt octacarbonyl precursors had to be firmly established. The kinetics of cobalt cluster formation has been thoroughly investigated, but data for iron pentacarbonyl decomposition is relatively scarce. To fully understand the formation of the iron nanoclusters, a kinetic study was performed by varying carbonyl concentrations and reaction media in order to establish reaction order and rate constants. Our results suggest this decomposition to be a higher order process (not first order as previously assumed), with a complicated intermediate mechanism, which has been postulated and experimentally verified. By using this kinetic data, we will be able to predict the necessary conditions for the creation of new in-situ iron-cobalt nanoalloys using carbonyl precursors.

Average Size

Monodisperse iron nanoparticles were prepared by thermal decomposition of iron carbonyl at low temperature of 160 oC - 180 oC in kerosene. The synthesized iron nanoparticles were spherical and their average size was decreased from 11.2nm to 8.6 nm as increasing the reaction temperature from 160 oC to 180 oC, respectively. The synthesized iron nanoparticles are amorphous, but the surface of the particles is easily oxidized and to be spinel structured iron oxide by HRTEM.
