High Catalytic Activity and Selectivity on Catalytic Denitrification by and Bimetallic Catalyst
Publication: Journal of Environmental Engineering
Volume 146, Issue 9
Abstract
This research focused on the improvement of catalytic activity and selectivity in catalytic denitrification by zero-valent iron () and bimetallic catalyst. Analysis of optimal operating conditions indicated that Pd-Cu/graphene showed better catalytic performance (catalytic activity: , selectivity: 70%) than other catalysts under the same following conditions: , catalyst, (Pd: 5% by weight), 2-h reaction time, and 5.1 pH. This may be due to graphene’s larger specific surface area, good chemical stability, thermostability, and strong electron transfer illustrated via characterization of , SEM, FTIR, and TG. Finally, experiments on regeneration and reuse of catalysts indicated that acidic washing helped to regenerate the catalysts. However, except for Pd-Cu/diatomite, the catalytic performances of other catalysts appeared to be lower than their original catalysts.
