Catalyst and its use in purification of contaminated water. # The present invention relates to a catalyst comprising a noble metal, preferably palladium, incorporated on indium oxide (In {sub, 2} O {sub, 3}), which It acts as a catalytic active support, its method of obtaining and its use in a process of purification of contaminated water. This catalyst is especially interesting for the elimination of nitrate (NO {sub, 3} {sup, -}), with selectivities reaching nitrogen gas (N {sub, 2}) high and close to 100% at high conversion values. |
