Preparation of ZnFe2O4/N-C catalyst and its catalytic performance of electrolyzed water

  • Received Date: 2020-01-10
  • Using polyaniline (PANI) as the matrix and carbon source, ZnCl2 and FeCl3 as the metal sources, ZnFe2O4 spinel compounds were synthesized in situ on the surface of PANI by hydrothermal method. The ZnFe2O4/N-C catalyst was prepared after carbonization at high temperature, its structure and morphology were characterized and analyzed, and the effect of carbonization temperature on the structure and performance of the catalyst was investigated. The results showed that the N-C in the catalyst ZnFe2O4/N-C mainly existed in the form of amorphous carbon. The ZnFe2O4 particles were highly dispersed on the N-C surface, and with the increase of the carbonization temperature, the crystallinity of ZnFe2O4 gradually increased; the introduction of ZnFe2O4 was beneficial to the catalyst ZnFe2O4/N-C graphitization degree, when n(Fe) : n(Zn)=2 : 1, the total concentration of metal ions was 0.1 mol/L, and the carbonization temperature was 800 ℃, the ID/I</i>G (the peak D-to-G peak ratio)value of the obtained catalyst ZnFe2O4/N-C-800 was 0.97, which was lower than the ID/IG value of N-C (1.12), and it had good catalytic performance for both hydrogen evolution and oxygen evolution reactions of electrolyzed water.
