Nanotechology Based Ambient Air Carbon Emission Investigation-Challenges Ahead

摘要

Nanotechnology could provide a solution to the soaring air pollution caused by automobile carbon emissions worldwide. Research showed that nano-treatment of engines could cut down toxic gas emissions. Also, use of nanotechnology-based systems increases the rate of pre-emission carbon trapping considerably. Nano-catalysts made from nanoparticles have a greater surface area to interact with the reacting chemicals than catalysts made from larger particles. Nanostructured membranes, on the other hand, are being developed to separate carbon dioxide from industrial plant exhaust streams. Also, it will create a method that can be implemented in any power plant without expensive retrofitting. This paper elucidates the use of carbon gas sensors for detecting carbon emission under deleterious conditions. The sensors used for detecting air pollutants are usually produced by coating a sensing metal oxide layer on a substrate with two electrodes. The general mechanism for a metal oxide sensor is a change in the resistance or conductance of the sensor when it is exposed to pollutant gas, relative to the sensor resistance in the ambient air. Internet geographical information system software applications can be generated by huge databases of spatial information from all relevant sources.
