Abstract:
Iranian researchers at University of Malayer and Material and Energy Research Institute of Iran used a layer nanohybrid compound to synthesize copper porous metallic nanopowder and they succeeded in the production of copper meso-porous nanopowder as well as carbonic microporous nanoparticles.

Concurrent Production of Metallic, Carbonic Porous Nanopowder by Layer Nanohybrid

Tehran, Iran | Posted on November 10th, 2011

"We synthesized meso-porous metallic nanopowder of copper in this research. To this end, we used a layer nanohybrid compound in order to produce the meso-porous metallic powder of copper," Dr. Mohammad Yeganeh Qotbi, member of the Scientific Board of University of Malayer, told INIC.

"Firstly, we synthesized a layer-like material from copper hydroxide," he added. "In the next stage, we inserted a carbonic source between the layers. The obtained compound is called nanohybrid."

"The nanohybrid was exposed to thermal treatment at 500įC. At this stage, the carbonic source converted into carbon and the layers of copper hydroxide into copper oxide. However, when the temperature reached 600įC, an internal carbo-thermal reaction took place. It means that the obtained carbon reacted with the produced copper oxide under argon atmosphere, and copper oxide reduced to metallic copper. The produced copper had a meso-porous structure."

Dr. Yeganeh Qotbi also pointed out that "the produced copper has such a high porosity that it is rarely observed even in the carbonic material. In addition, the pore size varies in the range of 2-50 nm".

According to Dr. Yeganeh Qotbi, the advantages of this research are simple production method, reasonable price, non-toxicity of the raw material, the ability to load high amount of carbonic material and the possibility to produce other porous metals.
