Abstract

The invention belongs to the technical field of nano composite preparation and relates to a nano iron-carbon composite powder preparation method. The nano iron-carbon composite powder preparation method is characterized by including the steps: taking ferric nitrate as an iron source, taking water-soluble organics as a carbon source, and preparing the ferric nitrate, the carbon source and a reducing agent into homogeneous aqueous solution; heating the solution to enable volatilization, concentration and decomposition of the solution to obtain a precursor; calcining in a reducing atmosphere to obtain nano iron-carbon composite powder, wherein metal iron particles of the nano iron-carbon composite powder are uniform and adjustable in size distribution, iron / carbon phases of the nano iron-carbon composite powder are uniform in distribution and adjustable in content, and iron particles of the prepared nano iron-carbon composite powder are smaller than 20nm. The nano iron-carbon composite powder preparation method has the advantages of easiness in material acquisition, equipment simplicity, short process, high efficiency, low cost and applicability to industrial production.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite material preparation, and in particular relates to a method for preparing nanometer iron-carbon composite powder. The method has simple equipment, short process flow, high efficiency and low cost, and is suitable for industrial production. technical background [0002] Nano-iron-carbon composite powder is a new type of multifunctional material uniformly compounded by nano-metal iron particles and carbon. Because the carbon layer is compounded around the nano-iron particles, the oxidation resistance and thermal stability of the nano-metal particles are improved, so that they can exist stably in the air for a long time, and the instability problem of the nano-metal iron particles is solved. Nano-iron-carbon composite powder not only has many excellent properties of nano-iron and carbon, but also has some new unique properties, so it shows great development potential and broad application prosp...
