A binary Mo/Fe-nitrogen-carbon material (MoFe-NC) catalyst was synthesized following the concept of biological nitrogen fixation. The MoFe-NC catalyst demonstrated a maximum N2 reduction faradaic efficiency of 39.9% and a NH3 yield rate of 28.5 μg mgcat−1 h−1 under ambient conditions. [ABSTRACT FROM AUTHOR]

The amorphous ZrF layer with various concentrations coated Li[LiMnNiCo]O cathodes were synthesized by using the chemical deposition technology. The combinations of XRD, SEM and TEM results indicated that the nanoparticles ZrF layer was successfully covered on the surface of the Li[LiMnNiCo]O particles. Compared to the pristine Li[LiMnNiCo]O, the cathodes after ZrF coating demonstrated the obviously enhanced electrochemical properties. The 2 wt% ZrF-coated Li[LiMnNiCo]O delivered a high capacity retention of 91.9% after 100 cycles at 0.5 C, much higher than that (84.5%) of the uncoated sample. Besides, the discharge capacity of 2 wt% ZrF-coated Li[LiMnNiCo]O was approximately 20.0 mAh g larger than that of the pristine Li[MnNiCo]O at various current densities. The EIS analysis indicated the remarkably enhanced electrochemical properties of the surface-modified electrode was ascribed to the fact that the ZrF coating layer could restrict the side reaction between cathodes with electrolyte and protect the cathode surface from HF corrosion, further accelerate the Li diffusion rate in the cathode.
