Stabilized Pony-Sized-CuFe2O4/Carbon Nitride Porous Composites with Boosting Fenton-like Oxidation Activity

In this study, pony-sized Copper ferrite (CuFe2O4) nanoparticles were directly obtained and synchronously stabilized on nanoporous carbon nitride (MCN) named as CuFe2O4-MCN, which emerges interestingly as a magnetically-recycling heterogeneous Fenton-like catalyst. The Fourier Transform Infrared, X-ray diffraction, N-2 desorption, X-ray photoelectron spectroscopy and transmission electron microscopy were seriatim used to characterize these synthesized functional catalysts. These present results demonstrated that CuFe2O4-MCN afford appreciable physical textural characteristics including well-defined porous structure, advisable surface area and pore volume. The interaction between CuFe2O4 and MCN and its induced improved dispersion of CuFe2O4 NPs on MCN could be confirmed through XPS, FT-IR, and TEM evidences. Impressively, the resulted CuFe2O4-MCN composites exhibited a three times' catalytic activity (k(obs), 0.076 min(-1)) than that (k(obs), 0.026 min(-1)) of mechanical mixture CuFe2O4-MCN(M) in 4-chlorophenol(CP) degradation. CuFe2O4-MCN porous composites was further evaluated in catalysis according to various controlled parameters, including catalyst loading, H2O2 concentration, catalyst dosage and pH of 4-CP degradation. At last, the catalytic stability of CuFe2O4-MCN composites was investigated via magnetic recycling and reusage in next catalytic test. After three successive experimental runs, the porous structure and catalytic activity of CuFe2O4-MCN catalysts remained constant.
