Synthesis of Mo 2 C@CeO 2 @Fe 3 O 4 particles for enhancing three-dimensional heterogeneous electro-Fenton degradation of MIT and HEDP
https://doi.org/10.1007/s11814-025-00386-4
Abstract
Mo 2 C@Fe 3 O 4 and three kinds of MO 2 -doped Mo 2 C@Fe 3 O 4 were successfully fabricated as the Mo 2 C@TiO 2 @Fe 3 O 4 ,
Mo 2 C@MoO 2 @Fe 3 O 4 and Mo 2 C@CeO 2 @Fe 3 O 4 particles for the degradation of 2-methyl-4-isothiazolin-3-one and
1-hydroxy-1,1-diphosphonoethane in a three-dimensional electro-Fenton system. The catalyst particles showed an enhancement
for the catalytic activity in the system. Furthermore, the Mo 2 C@CeO 2 @Fe 3 O 4 particles exhibited superior activity
for 2-methyl-4-isothiazolin-3-one and 1-hydroxy-1,1-diphosphonoethane degradation compared to the other two particles.
Based on the characterization of the synthesized particles, leaching concentration of Fe 2+ , generation of H2O2 , ∙ OH , O ∙−
2 ,
the reasons for the diff erence in pollutant degradation performance among the three type particles were comprehensively
analyzed. At last, some important experimental parameters, such as particles dosage, current density and aeration intensity,
which would obviously aff ect MIT and HEDP degradation performance were studied. Using the Mo 2 C@CeO 2 @Fe 3 O 4 as
catalytic particles, optimal 2-methyl-4-isothiazolin-3-one and 1-hydroxy-1,1-diphosphonoethane degradation rates were
97.2% and 73.8% with 0.5 g of particle dosage, 97.22% and 73.75% with 300 mA of current density, and 97.28% and 73.71%
with 0.1 L min −1 of aeration intensity.
