Nanocatalysts Find Application in Eliminating Air Pollution

Tehran, Iran | Posted on August 23rd, 2009

The Iranian Nanotechnology Initiative Council said that the Tabriz University research team has recently found a new way by which the air pollution caused by chemical and petrochemical industries can be reduced using nanocatalysts.

The team conducted a survey on catalytic oxidation of volatile organic compounds including oxygen compounds via improved ZSM-5 with Cobalt, copper, binary metal compounds and another survey on the effects of these nanocatalysts on removing these compounds.

"First, the improved ZSM-5 catalysts were synthesized with different percentages of Cobalt via wet impregnation, and then they were washed and dried. Next, noted nanocatalysts were fixed in a glass reactor in specific amounts," Aliqoli Niabi, senior member of the research team said.

Then in a catalytic oxidation set up, ethyl acetate polluted air flows with specific concentrations entered the reactor (at different temperatures), and were converted on the surface of catalysts. Finally, the outputs were analyzed by gas chromatography (GC) and GC-Mass, Niabi added.

Results demonstrate obtaining a rather more pure air. Now this team is applying the project on a power plant in Iran's northwestern province of Eastern Azerbaijan.
