ACTIVATED CARBON CLOTH-SUPPORTED BIMETALLIC Pd-Cu CATALYSTS FOR NITRATE REMOVAL FROM WATER

An activated carbon cloth-supported bimetallic Pd-Cu nanocatalyst is disclosed comprising about 1wt% Pd and about 0.35-0.45wt% Cu and having a surface Cu/Pd metal ratio of about 8-10 m2/m2. The nanocatalyst is capable of removing nitrate and/or nitrite from wastewater with a high selectivity to nitr...

Summary:An activated carbon cloth-supported bimetallic Pd-Cu nanocatalyst is disclosed comprising about 1wt% Pd and about 0.35-0.45wt% Cu and having a surface Cu/Pd metal ratio of about 8-10 m2/m2. The nanocatalyst is capable of removing nitrate and/or nitrite from wastewater with a high selectivity to nitrogen Cette invention concerne un nanocatalyseur bimétallique Pd-Cu supporté par un tissu de charbon actif, ledit nanocatalyseur comprenant environ 1 % en poids de Pd et environ 0,35 à 0,45 % en poids de Cu et ayant un rapport Cu/Pd de surface d'environ 8 à 10 m2/m2. Ce nanocatalyseur est capable d'éliminer les nitrates et/ou les nitrites des eaux usées avec une sélectivité élevée pour l'azote.
