Home > Press > Iranian Researchers Find Novel Method for Fabrication of Gas Nanosensors

Abstract:
Researchers at Iran's Materials and Energy Research Center (MERC) in collaboration with their colleagues at the University of Barcelona have recently managed to fabricate new sensors which feature better properties compared to their rivals in terms of response time and sensitivity.

Iranian Researchers Find Novel Method for Fabrication of Gas Nanosensors

Tehran, Iran | Posted on April 16th, 2012

Reproducibility, high efficiency and low cost and time of production are among other relative advantages of this new method.

Esmayeelzadeh, one of the members of the research group, explained, "Our work consisted of three major stages: characterization of the nanopowder used as the sensing material, layer deposition, and testing the performance of the sensor for detection of the pollutant gas nitrogen dioxide at various temperatures and concentrations. The layer deposition employed in this work was based on a low frequency alternating current. To our knowledge, such a method is novel and introduced for the first time by our research group."

In the proposed sensors, titanium oxide molecules are deposited on a layer of aluminum by a low-strength alternating field electrophoresis for practical detection of nitrogen dioxide. A set of experiments at dilute concentrations and varying temperatures (450-550 C) was conducted to conclude the desirable sensitivity of the fabricated nitrogen oxide gas sensors.

"The adopted method enables the control for configuration of the used nanoparticles, as the sensing elements, within the sensing layer. This would allow an optimal layer deposition and in turn performance. As a result, the current nanosensors can well compete with the conventional sensors available in the today market," Esmayeelzadeh added.
