Abstract

Well-crystallized CoFe2O4 and Ni-substituted Co1?xNixFe2O4 nanoparticles (x = 0.1, 0.3, 0.4, 0.5, 0.6, 0.8) were synthesized by continuous hydrothermal flow synthesis (CHFS). Catalytic properties of the synthesized nanoparticles in the catalytic oxidation of CO and electrochemical oxygen evolution reaction (OER) were studied. A conversion of 50?% in CO was reached at 223 °C and 100?% at 310 °C when CoFe2O4 prepared by CHFS was used as catalyst. The effect of Ni content on the OER activity of the as-synthesized Co1?xNixFe2O4 did not show a clear trend, however a remarkable improvement of the activity was observed for 30 at?% substitution (x = 0.3) in Co0.7Ni0.3Fe2O4.
