“…To compare the change of GO functional groups between before and after electrochemical deposition process, X-ray photoelectron spectrometry (XPS) C 1s spectra of the prepared GO and CdS/RGO/TNTs are displayed in Figure 2B. For the GO, four peaks at 284.5, 286.7, 287.5, and 288.9 eV, corresponding to C-C, C-O in hydroxyl or epoxy groups, C=O, and O-C=O, respectively [52,53]. While for the CdS/RGO/TNTs, the peak intensity of C-O and C=O are obviously lower than the GO, and that of C-C and O-C=O are unchanged, which is attributed to that the electric field of EPD process leads to the GO is partial reduced to be RGO, and the O-C=O is often hard reduced.…”

“…However, it also has some fatal disadvantages, such as poor mechanical properties and weak moisture resistance. One of the most effective ways to reinforce it is to incorporate it with inorganic nano‐ or micro‐fillers, for example, carbon nanotubes , graphene , nanodiamonds , metal oxide nanoparticles , layered silicates and others. However, the dispersion state of these fillers in the matrix, as well as the interface interactions, have great influence on the performance of the resulting composite films .…”

Montmorillonite (MMT) was modified by bio-inspired polydopamine (PDA) to obtain an exfoliated structure. Then, the modified MMT (MMT-D) and the original MMT were incorporated into starch to fabricate individual composite films. MMT lamellae were mostly intercalated in starch, while those of MMT-D were more likely to be exfoliated and presented better dispersibility, as revealed by the surface morphologies and XRD patterns of the composite films. Although MMT provided greater thermal protection to starch, MMT-D improved the tensile properties of the composite films more effectively. The composite film containing 2% MMT-D displayed a tensile strength as high as 8.1 MPa and a Young's modulus as high as 416.4 MPa, which were 2.1 and 3.8 times the values of the pure starch film, respectively. However, the composite films containing MMT had reduced tensile strength and modulus. This study showed that PDA pre-modification of MMT could improve the performance of starch-based nanocomposites, thus accelerating their acceptance in food packaging applications.

“…The first one is to synthesize pure BiOBr with various architectures, such as lamellas, hierarchical microspheres, microflowers, mesoporous microspheres, and self-assembled 3-D architectures [10][11][12][13][14]. Another alternative is relevant to the fabrication of BiOBr hybrids with other semiconductors of suitable energy-band structures and the obtained hybrids normally own unique optical and catalytic properties, thanking to the formation of a positive synergistic effect between these ingredients [15][16][17][18][19].…”

a b s t r a c tExfoliated g-C 3 N 4 (CNs)-BiOBr hybrids with heterojunction structure was fabricated through a chemical deposition-precipitation route. The characterization showed the uniform existence of CNs and BiOBr in hybrids. The fabricated CNs-BiOBr was of enlarged specific surface area, unique optical property, and well-matched energy-band structures. The photocatalytic performance on dye Rhodamine B (RhB) and 2,4-diclorophenol (2,4-DCP) were dramatically improved. Under identical conditions, sample 0.5CNs-BiOBr and CNs-BiOBr were identified as the best candidate, respectively, for catalytic degradation of RhB and 2,4-DCP. The former could show a reaction rate over RhB about 2.7 and 6.8 times as high as BiOBr and CNs alone, and the later exhibited a reaction rate over 2,4-DCP nearly 7.5 and 2.5 times as high as individual BiOBr and CNs. Finally, a possible catalytic mechanism was also proposed through active species trapping experiments.
