| Research Abstract |
Pollution of groundwater with nitrate caused by overfertilization is increasing problem in the world. Active carbon-supported Cu-Pd catalyst decomposed almost all nitrate into nitrogen gas by the hydrogenation in water. However, the Active carbon-supported Cu-Pd catalyst was remarkably deactivated by chlorine contained in groundwater for remediation of actual groundwater. In contrast, active carbon-supported Sn-Pd catalyst showed high catalytic performance even in the reaction solution containing chlorine and remediated the actual groundwater polluted with nitrate. The reaction system consisted of platinum-modified titanium oxide and Sn-Pd/Al_2O_3 promoted effectively photocatalytic reduction of nitrate in the actual groundwater.
