Rational design of FeS2 microspheres as high-performance catalyst for electrooxidation of hydrazine
文献摘要:
Inspired by the relatively recognized performance of transition metal sulfides in the oxidation of hy-drazine,the catalytic properties of FeS2 and Fe3S4 are compared via the density functional theory calcu-lations.Due to the different coordination numbers of iron-sulfur,the free energies of the dehydrogenation steps on FeS2 are far less than those on Fe3S4,which led to the much better catalytic performance of FeS2.Accordingly,FeS2 microspheres are rationally proposed as a more efficient electrocatalyst for hydrazine oxidation,which is then prepared by a facile one-step hydrothermal strategy.Such FeS2 microspheres show great activity for hydrazine oxidation with an onset oxidation potential of 0.22 V vs.reversible hydrogen electrode,and a peak current density of 16 mA cm-2.Meanwhile,stability and high faradaic efficiency(3.5e-/N2H4)is obtained for hydrazine oxidation to N2.
