Construction of Fe3O4@β-CD/g-C3N4 nanocomposite catalyst for degradation of PCBs in wastewater through photodegradation and heterogeneous Fenton oxidation

Dual-Mode-Driven Micromotor Based on Foam-like Carbon Nitride and Fe3O4 with Improved Manipulation and Photocatalytic Performance

“…The magnetization property of Fe 3 O 4 /f-C 3 N 4 was measured by a vibrating-sample magnetometer at room temperature. Figure d shows that the magnetic hysteresis loop curve of Fe 3 O 4 /f-C 3 N 4 is symmetric with a saturation magnetization value of 18.6 emu g –1 , indicating the superparamagnetic character and excellent magnetic controllability . The magnetic property of Fe 3 O 4 /f-C 3 N 4 allows the easy separation after use by a permanent magnet.…”

A Review of Activation Persulfate by Iron-Based Catalysts for Degrading Wastewater

“…However, since Fe 3 O 4 is easy to accumulate in solution and contact sites are reduced after agglomeration, single Fe 3 O 4 is rarely used. Using the composite carrier method [93] can not only solve these problems, but also speeds the reaction rate, making it more cost effective when applied in industrial production. He et al [94] pointed out that the Fe 3 O 4 /GO/Ag composite microspheres are formed using magnetic Fe 3 O 4 as cores, followed by coating an internal layer of GO and an outer layer of Ag nanoparticles, as Figure 8 shows.…”

A novel g-C3N4 nanosheet/Ag3PO4/α-Bi2O3 ternary dual Z-scheme heterojunction with increased light absorption and expanded specific surface area for efficient photocatalytic removal of TC

“…15 Morphology modification and construction of heterojunctions are effective strategies to overcome these shortcomings. 16,17 Compared with bulk g-C 3 N 4 (BCN), 2-dimensional (2D) layered g-C 3 N 4 nanosheets (CNN) exhibit significantly higher intrinsic light absorption and response than BCN because of the enhanced p-orbital hybridization of C and N. 18 In addition, the photoexcited charge carriers generated inside the 2D nanosheets were more easily transferred to the surface than that of BCN, which improved its charge conduction and separation ability. 19 Furthermore, CNN can greatly increase the specific surface area and expose more active sites, which is favorable for contact and hybridization with other components to form composite materials.…”
