Abstract
About this talk
In recent years, the rapidly increment in industrial emissions, vehicle exhaust and open burning of garbage waste are the main cause of pollutants gases which regularly deteriorate the natural environmental conditions. The continuous monitoring of these pollutant gases (H2, CO & NOx) is necessary to prevent environmental deterioration. Various types of instruments and materials are available to monitor the pollutes and harmful gases. Among materials, carbon materials are widely investigated because of they are enormously to these pollutants gases at room temperature conditions. In the present work, the cost-effective candle carbon soot (CCS) is used to detect 0.5% concentration of H2 gas at room temperature. A simple candle flame is used to synthesize the layers of carbon soot at room temperature conditions. The acid treatment of the CCS at room temperature was drastically improved their structural and sensing properties as compared to as-synthesized CCS. To the best of our knowledge, detection of low concentrations of H2 gas is reported here for the first time using economical CCS at room temperature. These results are important for developing a new class of chemiresistive type gas sensor based on change in the electronic properties of the CCS.
