Abstract

Abstract

To solve the problem of high nitrate content of groundwater, bimetal Pd-Cu@UiO-66 catalyst was prepared for the catalytic reduction of nitrate in water for the first time. The influence of the carrier synthesized with different regulator and process conditions on denitrification performance was investigated. The results showed that the nitrate removal rate was 97.4%, and N₂ selectivity was 95.2% when the UIO-66 carrier was prepared by hydrochloric acid with the loading of 1% Pd and 1% Cu and the hydrogen flow rate was 70 mL/min. The carrier prepared with the modulator of lower pKa had the smaller particle size, which was conducive to the formation and dispersion of smaller active metal particles. The high dispersion of active metal was beneficial to the generation of activated hydrogen and the electron transport of Cu, and to improve the selectivity of nitrogen in denitration reaction. During the reaction, the bimetallic synergic effect was the key factor affecting the catalytic performance.
- nitrate removal,
- MOFs material,
- Pd-Cu catalyst,
- metal particle size
