<b>Abstract:<p align=\"justify\"> <br /> Oxides of nitrogen such as nitric oxide (NO) and nitrogen dioxide (NO2) are important air pollutants, because they have significant harm to human health and play an important role of being precursor of photochemical smog. Nitrogen oxide are formed fossil fuel combustion, exspecially to power plant and mobile sources. To anticipate the rapid increase of NOx concentration, it is important to develop an alternative technology in NOx abatement.<p align=\"justify\"> <br /> The catalytic process using uv light and semiconductor particle, such as titanium dioxide and ferric dioxide is promising alternative of abatement. <br /> A mixture of TiO2 and Fe2O3 was found to be excellent photocatalyst for removal of low concentration NOR. Addition of a small of Fe2O3 to TiO2 could enhance the catalytic activity. <br /> The photocatalytic degradation of oxide nitrogen (NOx) by titanium dioxide and ferric dioxide irradiated with light at the wavelength of 360 nm was studied in a continous flow-through reactor spiral-path. The effects of modifications were investigated.<p align=\"justify\"> <br /> The result of the research showed that illuminated TiO2 and Fe2O3 particles were able to reduce NOx to the significant value. TiO2 and Fe2O3 powder which was coated on the spiral-path reactor wall showed much better photocatalytic activities with pure gas compared with coal burning of gas. Gas from coal burning content another gas, such us sulfur dioxide and carbon oxide which was can decreased removal efficiency NOx.
