Removal of nitrate in water by hydrogenation with a noble metal-free Ni-base catalyst
Porous Ni catalyst modified with a small amount of Zr was found to be highly active for hydrogenation of nitrate (200 ppm) in water at 333 K. This is the first example of noble metal-free catalyst effective for this reaction.
