“…The areas of the three C 1s components showed that the nonoxygenated ring C (C−C) is about 49.4% for GO, while 87.1% for rGO ( Figure 3). These results reveal that most of the oxygen functional groups in GO were removed, 24 and this is in accordance with UV−vis and FT-IR results.…”

In this study, we prepared stable reduced graphene oxide (rGO) solutions with renewable resource quaternized chitosan (QCS) and layered silicate as green reducing and stabilizing agents. Rectorite (REC) and organic rectorite (OREC) are typical layered silicate employed in this work. UV−visible absorption spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy results showed the good reducing effect of QCS to produce rGO. Transmission electron microscopy, atomic force microscope, and X-ray diffraction results showed that rGO nanosheets were loaded with layered silicate through cation exchange to get a rGO/QCS/layered silicate composite. The high zeta potential (+41.4 mV) of the rGO/QCS composite showed the good stabilizing effect of QCS, and the higher zeta potential of rGO/QCS/OREC (+38.5 mV) than that of rGO/ QCS/REC (+37.3 mV) indicated that OREC had a better stabilizing effect than REC. The possible assembly mechanism of the rGO/QCS/layered silicate composite was electrostatic interaction and cation exchange. The addition of the layered silicate improved the thermal stability of the composite, and rGO/QCS/OREC showed high uptake (425 μg/mg) toward doublestranded DNA (dsDNA).

“…Besides, Mn oxides 43 have a poor electronic [12] and ionic conductivity [13,14]. Recently, 44 researchers find that binary metal oxides are quite intriguing 45 from the perspectives of both fundamental science and technology 46 because the composite can enable versatile and tailor-made prop-47 erties with performances far beyond those of monometallic oxides 48 [15]. For example, according to relevant literature [16], binary 49 metal oxides may possess a higher electronic conductivity and 50 higher electrochemical activity than those of monometallic oxides.…”

“…The RGO and IRGO were exfoliated, centrifuged and the colloidal sediments were dried for XRD samples preparation. The RGO and IRGO curves exhibit a broad halo in the range 20-40 • indicating that the stacked sheets are exfoliated in their individual nanosheets [24]. The lower intensity halo for IRGO compared with RGO indicates a more amorphous structure.…”
