“…9b, under UV light irradiation, 93 % of the MB dye was decomposed after irradiation for 100 min. This indicates that the CNC/ZnO nanohybrid showed high photocatalytic activity due to the strong electronic interaction between the CNCs and ZnO nanoparticles; a similar phenomenon was found for ZnO/reduced graphene oxide (RGO) composites (Huang et al 2014;Zhang et al 2012). Moreover, the photocatalytic activity of the CNC/ZnO nanohybrid was higher than that for ZnO nanoparticles coated on cellulosic fibers (Fallah et al 2011).…”

Cellulose nanocrystal/zinc oxide (CNC/ ZnO) nanohybrids were prepared through citric hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and simple precipitation with zinc nitrate aqueous solution [Zn(NO 3 ) 2 Á6H 2 O] via one-pot green synthesis, in which preparation and modification of CNCs were performed simultaneously and the obtained CNCs with carboxyl groups could act as a stabilizing and supporting agent to anchor ZnO nanoparticles. The influence of the Zn 2? ion concentration on the morphology, microstructure, and properties of the CNC/ZnO nanohybrids was investigated by using Fourier-transform infrared and ultravioletvisible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, field-emission scanning electron microscopy, and thermogravimetric analysis. According to the UV-Vis and XRD results, well-dispersed ZnO nanoparticles with hexagonal wurtzite structure and smallest average diameter of 42.6 nm were successfully anchored onto the surface of the CNCs. The CNC/ ZnO nanohybrid CNC/ZnO-0.5 showed improved thermal stability, high antibacterial activity, and photocatalytic activity for methylene blue (MB) due to strong interaction between the CNCs and ZnO nanoparticles. Compared to CNCs, the thermal degradation onset temperature (T 0 ) of the nanohybrids was increased by 23.9°C, while antibacterial ratios of 100.0 and 100.0 % against viable Escherichia coli and Staphylococcus aureus were achieved. Moreover, 93 % of MB dye was decomposed after UV light irradiation for 100 min.

Kavitha et al reported the in-situ hydrothermal synthesis of ZnO nanocrystals decorated graphene hybrids which display a strong and broad absorption in the visible region besides an intense UV absorption peak [16].…”

“…However, the disappear of peaks located approximately 9°revealed that most of the oxygen containing functional groups in GO were removed during the high temperature sintering process [24] and one small peak located at 26°ap-peared in XRD spectrum of ZSwG10 ceramic composites, which indicated that GO was thermally reduced to graphene nanosheets. As reported previously, the strong (002) reflection (2θ $ 26°) was a result of wave interference between scattering by different graphene layers [25][26][27].…”

a b s t r a c tUltrahigh temperature ZrB 2 -SiC w -Graphene ceramic composites are fabricated by hot pressing ZrB 2 -SiC w -Graphene oxide powders at 1950°C and 30 MPa for 1 h. The microstructures of the composites are characterized by Scanning electron microscopy, Raman spectroscopy and X-ray diffraction. The results show that multilayer graphene nanosheets are achieved by thermal reduction of graphene oxide during sintering process. Compared with monolithic ZrB 2 materials, flexural strength and fracture toughness are both improved due to the synergistic effect of SiC whisker and graphene nanosheets. The toughening mechanisms mainly are the combination of SiC whisker and graphene nanosheets crack bridging, pulling out.
