“…The bimetallic structure can enhance the activity and stability of copper based catalysts due to the formation of copper−metal bonds in PMS activation. 12 Spinels, a kind of bimetallic catalysts mostly composed of AB 2 O 4 (where A and B are metal ions), have been studied in various fields due to their manifold valence states, electron configurations, and compositions. 13 CuFe 2 O 4 is a typical spinel that can enhance pollutant degradation via catalytic ozonation, 14 microwave radiation, 15 photocatalysis, 16 and Fenton-like reaction.…”

Design of the low-cost and environmentally friendly catalyst for advanced oxidation processes is highly desired in environmental remediation. Herein, a flower-like CuFe2O4 nanostructure is synthesized by a self-templating method for the first time and used for the activation of peroxymonosulfate (PMS) to degrade carbamazepine (CBZ). The catalytic performance of the flower-like CuFe2O4 is much higher than that of the other CuFe2O4 structures (nanoparticles, bulk, and sphere). 90% of CBZ (10 mg/L) can be degraded by adding 0.1 g/L of CuFe2O4–16–350 and 0.2 g/L PMS, and 50% of TOC got removed in 120 min. After five consecutive cycles, the CBZ removal efficiency by the flower-like CuFe2O4 still remains at 66%. Kinetic behavior of CBZ degradation follows the pseudo-first-order reaction model, and the reaction rate constant value of the flower-like CuFe2O4 is 3.7 times higher than that of CuFe2O4 nanoparticles. The structure-dependent catalytic activity of CuFe2O4 catalysts is investigated by experiments and characterizations such as BET, XPS, and H2-TPR. The results show that the excellent catalytic performance of the flower-like CuFe2O4 is mainly attributed to the strong interaction of dual metal species in it apart from its high specific surface area and large pore volume. A reasonable mechanism of PMS activation is established on the basis of the characterizations of catalyst, radical determination, and the identification of intermediates. This work provides a novel strategy to develop a highly efficient and stable spinel catalyst for pollutant degradation through PMS activation.

“…Majority of researches focused on seeking electron donors to reduce Cu(II) to Cu(I) for the acceleration of the Cu(II)/Cu(I) cycle, such as adding UV/visible light irradiation, harnessing the synergistic effect of metal ions, ,− introducing reagents to promote the circulation of copper species , or the electrophilic properties of pollutants . However, the active components of the majority of catalysts composed of metal ions still suffer heavy metal leaching during catalysis reactions, which run counter to the original intention for heterogeneous catalyst preparation, limiting large-scale application.…”

Heterogeneous catalysis can be enhanced through the construction of effective atom connection for rapid electron transport on the catalyst surface. Hence, this study proposed a new strategy for electron transfer regulation to facilitate redox cycle of Cu(II)/Cu(I). The objective was achieved by successful construction of copper-containing covalent bond through the in situ growth of porous g-C 3 N 4 with oxygen dopants and nitrogen defects (O-CN D ) on CuAl x O y substrate (CuAl@O-CN D ). On the basis of X-ray absorption fine structure (XAFS) and other characterization results, the facilitated redox behavior of copper species by electron transfer regulation was ascribed to the formation of a C−O−Cu bond on the porous-rich superficial of the catalyst; these covalent C−O−Cu bonds shortened the migration distance of electrons between Cu(II) and Cu(I) via Cu(I)−O−C−O−Cu(II) bridge. The construction of copper-containing covalent bonds in the catalyst resulted in efficient PMS activation for a rapid redox cycle of Cu(II)/Cu(I), triggering a series of reactions involving the continuous production of three highly active species (SO 4 •− , • OH and 1 O 2 ). The rapid diffusion and transportation of the generated active species from porous structures directly attack typical pharmaceutically active compounds (PhACs), achieving superior catalytic performance. This study provides a new routine to construct a C−O−Cu bond for PMS activation by regulating the electron transfer to accelerate the redox behavior of copper species for environmental remediation.

“…Furthermore, the components of FC are mainly Fe 2+ , Fe 3+ , Cu 0 and Cu 2+ with strong electron migration rate and antibacterial activity, and because it contains Fe and Cu elements, it can have a certain promotion effect on plant growth at moderate concentrations, and plants have different requirements for Fe and Cu elements during the growth process, and the application of different elements at the growth stage for the application of different elements at the growth stage has important research and practical value for plant growth, which we will explore in further studies. In addition, if Fe 3 O 4 is used as the nucleus and Cu 0 and Cu 2+ or Cu 2+ and Cu 0 are loaded on the surface in turn due to Fenton reaction and interfacial effect can produce a certain amount of ROS, [42][43][44] theoretically, it can have some antibacterial activity because Cu 0 and Cu 2+ have different redox potentials and can spontaneously carry out redox reactions to produce more free electrons and Cu intermediates and cause more damage to bacteria, so it is important for bacterial inhibition research and application. However, this material needs to be synthesized by layer assembly, multi-step reaction, and exhaustive characterization and antibacterial activity testing, while the present material is a composite of four elements, Fe 2+ , Fe 3+ , Cu 0 and Cu 2+ .…”
