Fig. 3: Reconstruction analysis of Co6Ni4 during NO3RR.
From: Revealing and modulating catalyst reconstruction for highly efficient electrosynthesis of ammonia
In situ Raman spectra of a Co and b Co6Ni4 catalysts during NO3RR (potentials are not iR-corrected). Electrochemical operando XANES for Co K-edge of c Co and d Co6Ni4 catalysts (potentials are not iR-corrected). e The Co K-edge absorption energy from the operando XANES spectra of Co6Ni4 and Co catalysts (potentials are not iR-corrected). f Operando XANES for Ni K-edge of Co6Ni4 catalyst (potentials are not iR-corrected). g The Rct of prepared catalysts in NO3RR against applied potential (without iR compensation). h The comparison of the conductivity of Co6Ni4, Co, and Ni catalysts. The error bar represents the standard deviation of the data from three independent experiments. i The potential-dependent adsorption capacity of NO3- on Co6Ni4, Co, and Ni catalysts (potentials are not iR-corrected). Source data for the above figures are provided as a Source Data file.
