N2 - Photocatalytic reduction of NO 3 - under UV irradiation in the presence of ethanol was carried out in the presence of semiconductor photocatalyst Pt/TiO 2 and supported bimetallic non-photocatalyst Sn-Pd/Al 2O 3, which were dispersed in water. This system effectively and selectively promoted the photocatalytic reduction of NO 3 - to N 2, whereas Pt/TiO 2 or Sn-Pd/Al 2O 3 alone showed no or little activity under the reaction conditions. The decomposition rate of NO 3 - and selectivity to gaseous nitrogen compounds (mainly N 2) for the present photocatalytic system were higher than those for TiO 2 photocatalyst directly-modified with Sn-Pd particles.
