The activities and selectivities of Pd–Cu and Pt–Cu bimetallic catalysts supported on different carbon materials (activated carbons with different surface chemistries, multiwalled carbon nanotubes and carbon xerogels) were studied in the catalytic reduction of nitrate in water. The surface chemistry of the support has an important role in the catalyst activity and selectivity, being its influence...
Ten monometallic and 13 bimetallic catalysts supported on activated carbon were assessed, the former in the reduction of nitrate or nitrite and the latter in the nitrate reduction. Under the conditions used, nitrite was shown to be reduced by monometallic catalysts. With exception of Ru, only some of the bimetallic catalysts were able to reduce nitrate. Rh–Cu shows the highest conversion, but Pd–Cu...
