Abstract
The influence of magnetic induction heating on the catalytic activity of cobalt ferrite has been investigated. The cobalt ferrite has been obtained by flow co-precipitation method using metal salts as precursors and sodium hydroxide as precipitant. The catalytic activity of CoFe2O4 has been studied in the H2O2 decomposition. The influence of the catalyst dosage and its annealing temperature on the H2O2 decomposition has been studied. The impact of induction heating on cobalt ferrite activation has been elucidated. It is shown that the CoFe2O4 catalyst, annealed at 400 °C, exhibited the highest catalytic activity under induction heating in the H2O2 decomposition for 20 mM H2O2 solution. Induction heating is proposed as a promising approach for use in water purification technology.
