Precursor chain length dependence of polymeric precursor method for the preparation of magnetic Fenton-like CuFe2O4-based catalysts
Source abstract
Abstract
Heterogeneous Fenton-like catalysts based on CuFe2O4 were prepared by polymeric precursor method, using various polyhydroxy alcohols as polymeric agents: ethylene glycol, diethylene glycol and triethylene glycol. These catalysts were, respectively, characterized by XRD, SEM, pHPZC and VSM measurements. All catalysts showed typical ferromagnetic properties and highly catalytic activities for the degradation of methylene blue. When the chain length of polyhydroxy alcohols increased, the pHPZC value and particle size of these catalysts were not significantly modified, whereas the percentage of CuFe2O4 tetragonal spinel phase decreased, leading to the decline of catalytic activity and the reduction in coercive field.
