## Title

    synthesis
  title_type: original

## Description

- description: Electrocatalytic urea synthesis from CO2 and NO3- are environmental
    green and energy savable. Although Cu are effective for CO2 and NO3- reduction
    reactions, achieving high efficiency of urea production remains challenging. Herein,
    Cu-Ni nanocrystals are formed to provide heterogenous active sites for promoting
    hydrogenation and C-N coupling reactions in urea synthesis. The carbon supported
    Cu-Ni nanocrystals are characterized by extended X-ray absorption fine structure
    and X-ray photoelectron spectroscopy spectra. The Cu-Ni nanocrystals achieves
    the highest urea Faradaic efficiency of 25.1 % and urea yield of 22.01 μmol h-1
    cm-1, which is much higher than that of single Cu or Ni metal. The reaction mechanism
    is probed by in-situ Fourier transform infrared spectroscopy, revealing a C-N
    coupling reaction pathway between *CO and *NH2. Theoretical calculations suggest
    that hydrogenation of *NOx and coupling *CO with *NH2 are more easily occurred
    over co-existed Cu and Ni sites rather than homogeneous Cu or Ni site.
