Abstract

Abstract : Well‐crystallized CoFe2 O4 and Ni‐substituted Co1– x Ni x Fe2 O4 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 CoFe2 O4 prepared by CHFS was used as catalyst. The effect of Ni content on the OER activity of the as‐synthesized Co1– x Ni x Fe2 O4 did not show a clear trend, however a remarkable improvement of the activity was observed for 30 at % substitution ( x = 0.3) in Co0.7 Ni0.3 Fe2 O4 .
