Abstract:
Iranian researchers at Tehran University succeeded in synthesizing lower-cost catalytic converters embedded with metal oxide nanoparticles to eliminate exhaust pollutants of gas-powered vehicles.

Metal Oxide Nanoparticles Used to Produce Low-Cost Catalytic Converters

Tehran, Iran | Posted on July 3rd, 2011

"Methane and carbon monoxide are the major pollutants of gas driven vehicles and their emission amounts shall conform to environmental codes/standards. Therefore, catalytic converters come in handy in removing such compounds," Hesam Ziayee, PhD candidate at University of Alberta, Canada, explained.

"The main component of these converters consists of valuable metals like palladium and platinum used to break down the exhaust pollutants to least hazardous carbon dioxide."

"We sought an appropriate mixture of metal oxide nanoparticles to remove methane and carbon dioxide from the exhaust gases," he added.

"We made it to prepare the desired nanocatalysts through the combustion synthesis method", Ziayee said, adding, "During the course of our research, we benefited from the facilitation in synthesis of the nanoparticles provided by an innovative use of macrowaves. In the second phase, we examined the performance of the prepared nanoparticles in removal of a model gaseous flow simulating the real exhaust emissions of gas powered engines."

The researchers also managed to reduce the amount of valuable metal raw materials for this application to a great extent without sacrificing the performance of the catalysts involved. The proposed mixture is comprised of iron and lanthanum oxides plus a minute percentage of palladium.
