Investigating the effect of gas flow rate and amount of zinc oxide nanoparticles on the efficacy of photocatalytic oxida
Journal Title: Scientific Journal of Review - Year 2015, Vol 4, Issue 7
Abstract
Nitrogen oxides are one of the most important air pollutants in environment and industrythat due to the adverse health and environmental effects should be refined before discharging into the environment. The photocatalytic oxidation method of nitrogen oxide into nitrogen Dioxide for better absorption insolutions is a promising method for removing of nitrogen oxides. Laboratory system used in this study is included of a source of gas source, mixing chamber, photocatalytic oxidation reactor, measuring system for nitrogen oxidation. Zinc oxide nanoparticles which were simulated by UV-A radiation would be used for photocatalytic oxidation. Inlet concentration of nitrogen oxide and the amount of stabilized nanoparticles in reactor for converting nitrogen oxide into nitrogen dioxide has been investigated. Results showed that the amount of monotonic converting of nitrogen oxide into nitrogen dioxide in the amount of Nano-particles is stabilized 8mg/cm2 for inlet concentration 100,150,200 ppm and respectively equivalent to 15, 26 and 32%. This study showed that increasing concentration of inletnitrogen oxide in system, reduce the capacity of photocatalytic oxidation for converting nitrogen oxide into nitrogen dioxide.
