For the catalyst with the optimum Sn\/Pd molar ratio, the surface concentration of adsorbed nitrogen on the Pd sites is thought to be high and that of the adsorbed hydrogen on the Pd sites is thought to be low. This is due to the abundant supply of NO<sub>2<\/sub><sup>&#8211;<\/sup>for the Pd sites and the prompt consumption of adsorbed H on the Pd sites for reduction of the oxidized Sn sites formed by the reduction of NO<sub>3<\/sub><sup>&#8211;<\/sup>, respectively, leading to the high selectivity to gaseous products. Although the catalytic performance of Sn<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>, like that of Cu<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>, was lower in groundwater, the decrease for Sn<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>was less than that for Cu<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>. Nitrate in the groundwater polluted with 0.4 mmol dm<sup>&#8211;<\/sup><sup>3<\/sup>(250 cm<sup>3<\/sup>) of NO<sub>3<\/sub><sup>&#8211;<\/sup>was completely reduced at 298 K in 24 h with a selectivity for gaseous products of around 90% in the presence of 10 mg of Sn<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>, whereas it took 60 h in the presence of Cu<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>, and the selectivity for gaseous products was around 75%. However, both catalysts showed comparable high activity and high selectivity in aqueous NO<sub>3<\/sub><sup>&#8211;<\/sup>solutions. When reactions were performed in aqueous NO<sub>3<\/sub><sup>&#8211;<\/sup>solutions containing other anions (Cl<sup>&#8211;<\/sup>, SO<sub>4<\/sub><sup>2<\/sup><sup>&#8211;<\/sup>, and SiO<sub>x<\/sub><sup>n<\/sup><sup>&#8211;<\/sup>) present in the groundwater, Cl<sup>&#8211;<\/sup>had the largest negative impact but it had a smaller impact in the presence of Sn<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>than it did in the presence of Cu<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>. On the basis of adsorption isotherms for Cl<sup>&#8211;<\/sup>and kinetics analysis of the hydrogenation of NO<sub>3<\/sub><sup>&#8211;<\/sup>, it was concluded that Sn<sub>0.5<\/sub>Pd\/Al<sub>2<\/sub>O<sub>3<\/sub>had less affinity for Cl<sup>&#8211;<\/sup>and a strong affinity for NO<sub>3<\/sub><sup>&#8211;<\/sup>on the Sn sites, leading to its superior catalytic performance in groundwater.\n        <\/li>\n<li><b>&#8220;Determination of acid site location in dealuminated MCM-68 by Al-27 MQMAS NMR and FT-IR spectroscopy with probe molecules&#8221;<\/b><br \/>Ryoichi Otomo, Toshiki Nishitoba, Rota Ogusa, Yusuke Kunitake, Yuichi Kamiya, Takashi Tatsumi, Toshiyuki Yokoi<br \/><i>J.
