Nanocatalysts could be helpful in reducing air pollution

(Nanowerk News) A research team at the chemical process technology laboratory of Tabriz University, Iran found solutions for reducing emissions of volatile organic compounds in air ("Catalytic Combustion of Ethyl Acetate over Nanostructure Cobalt Supported ZSM-5 Zeolite Catalysts").
They have recently found a new way by which the air pollution caused by chemical and petrochemical industries can be reduced using nanocatalysts.
In this project, 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 were conducted.
"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," Aligholi 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, at last the outputs were analyzed by gas chromatography (GC) and GC-Mass, Niabi added.
Results demonstrate obtaining a rather a more pure air. Now this team is applying the project on a power plant in East Azerbaijan.
