Photocatalytic Removal of NOx Gas from Air by TiO2/Polymer Composite Nanofibers

Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...

A Reactivity Based Emission Inventory for the South Pars and Its Implication for Ozone Pollution Control

The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to substantial ozone production downwind. To understand the role of these emissions on the ozone formation and, to formulate appropriate control st...

Determination of nitrogen oxides in ambient air using a coated-wire nitrate ion selective electrode.

A Multi Wavelength Approach to the Retrieval of Tropospheric No2 from Gome Measurements

Nitrogen oxides play an important role in the chemistry of earth’s atmosphere. In the troposphere, they provide the only chemical source for ozone, arguably the most important radical in the lower atmosphere. Nitrogen oxides are central in the formation of photochemical smog in the industrialised countries and also in regions with intense biomass burning. In addition to its relevance to troposp...

Solid state chemistry of nitrogen oxides--part I: surface consumption of NO.

The role of nitrogen and oxygen chemistry in the interstellar medium is still rather poorly understood. Nitric oxide, NO, has been proposed as an important precursor in the formation of larger N- and O-bearing species, such as hydroxylamine, NH2OH, and nitrogen oxides, NO2 and N2O. The topic of this study is the solid state consumption of NO via oxygenation and the formation of NO2 and other ni...
