In this work, the humic acid (HA)-modified g-C 3 N 4 -supported hydrotalcite-like compounds (g-C 3 N 4 @HTLcs/ HA) was successfully synthesized, characterized, and further applied to remove 2,4-dichlorophenol (DP), glyphosate (GH), and tetracycline (TL) from aqueous solution. The results showed that g-C 3 N 4 @HTLcs/HA had obvious layered structure, and a large amount of HA was successfully loaded on the surface. When HA concentration was 100 mg L −1 , the adsorption capacity of DP, GH, and TL was relatively high. The optimal pH range of TL adsorption was 7−9 and that of DP and GH were 3−9, and the influence of ionic strength on the adsorption of g-C 3 N 4 @HTLcs/ HA100 was limited. The isotherm experimental data of TL, GH, and DP adsorption onto g-C 3 N 4 @HTLcs/HA100 were best fitted by Freundlich and Langmuir models. The adsorption of TL, DP, and GH was all consonant with the pseudo-second-order kinetic model and spontaneous endothermic process. Based on the mass transfer theory, the diffusion of TL, DP, and GH on the adsorption process under liquid film control was derived. The adsorption mechanism might be the ion exchange between the layers of hydrotalcite, and the surface complexation and hydrogen bonding between various groups of HA and organic contaminants. This work suggested that g-C 3 N 4 @HTLcs/HA100 was effective in treatment of water containing various organic pollutants.

“…In the XRD patterns of Figure 1b, a characteristic peak of graphene oxide (GO) at 11.7 corresponds to its (002) crystal plane, and the diffraction peaks of MgAl-LDH at 11.4, 23.1, 34.3, 38.6, 45.8, 60.5, and 61.8 correspond to (003), ( 006), (012), ( 015), ( 018), (110), and (113) crystal surfaces, respectively. 44 The characteristic peaks of MgAl-LDH also appear in the hybrid filler MgAl-LDH/rGO-s, which also proves the successful synthesis of MgAl-LDH and the successful loading on GO. The filler was calcined at 600 °C for 8 h in a tubular furnace; the characteristic peak of rGO could be seen from XRD at 21°, which was significantly higher than that of GO, indicating the disappearance of functional groups on the surface of GO and the successful preparation of rGO.…”

“…After calcination, the (111), (200), and (220) characteristic peaks of Mg(Al)O appear, while the characteristic peak of LDH disappear, indicating that the precursor MgAl-LDH was successfully transformed into MgAl-LDO. 44,45 The phenomenon is also reflected in the infrared spectrum (Figure 1c). The characteristic peaks of typical nitrates, O−M−O and M−O (M = Mg, Al) in MgAl-LDH, can be seen below 400−800 cm −1 through the FTIR spectra, while these characteristic peaks are weakening in MgAl-LDO.…”

Research and development of polymer composites with high thermal conductivity and excellent electrical insulation are one of the research hotspots in thermal management. Although the thermal conductivity issue has been improved effectively with many methods, it remains challenging due to the interface thermal resistance issues and how to hold the electrical insulation performance at high thermal conductivity. Herein, MgAl layered double oxide/reduced graphene oxide (MgAl-LDO/rGO-s) with a hierarchical structure was innovatively used in the CNF thermal conductivity field. The lamellar structure and strong interfacial interactions between MgAl-LDO and rGO construct the continuous thermal conduction path for phonons transport, and the interface thermal resistance is effectively reduced. Meanwhile, the insulated MgAl-LDO forms a hierarchical structure on the surface of rGO by its positive charge characteristics and keeps excellent electrical insulation properties. Therefore, the CNF/MgAl-LDO/rGO-s composite films exhibit high in-plane thermal conductivity (8.7 W·m–1·K–1), electrical insulation (ρv > 1013 Ω·m), and excellent thermal stability. This work provides an interface engineering strategy for heat conduction and electrical insulation and broadens the upper limit application of thermally conductive polymer composites (TCPC) in thermal management.

“…Table 1 lists the comparative maximum adsorption ability between the Mn-rich limonite and other previously reported adsorbents. Although the experimental conditions were different, one should be noted that the q m of limonite was relatively encouraging compared to other adsorbents such as MgAl layered double oxide (Zhang et al, 2020). This finding demonstrated that the Mn-rich limonite was a promising adsorbent for TC removal from aqueous solution.…”

Naturally occurring Mn-rich limonite mainly composed of goethite and manganese oxides was used to remove tetracycline (TC) from the aqueous solution. The physicochemical properties of limonite were illustrated by various characterization techniques such as XRD, FE-TEM, XPS and FT-IR. The effects of dosage, initial solution pH, temperature and coexisting anions on TC removal were investigated. The results showed that TC could be efficiently adsorbed by limonite with high specific surface area and mesoporous structure through electrostatic interaction and complexation. The co-existence of PO43- inhibited the adsorption of TC by limonite due to the competition with TC for active sites. In addition, manganese oxides exhibited oxidative properties to TC, and the singlet oxygen (1O2) generated during the redox reaction was responsible for TC degradation. Furthermore, the regenerated limonite displayed an efficient recycling performance after four cycles. This study revealed that the Mn-rich limonite was a promising adsorbent for TC removal from aqueous solutions and promoted the application of natural mineral material in the environmental field.
