文摘
- •
Highly-active and nitrogen selective Pd–Cu/γAl2O3 catalyst was prepared.
- •
A novel electrochemical-catalytic (ECC) nitrate reduction system was developed.
- •
H2 was generated on cathode surface and served as reductant in catalytic reaction.
- •
NO3− removal rate, N2 selectivity, and current efficiency were enhanced in ECC.
