Data from: Irradiation-catalyzed degradation of methyl orange using BaF2-TiO2 nanocomposite catalysts prepared by a sol–gel method
BaF2-TiO2 nanocomposite material (hereinafter called the composite) was prepared by a sol–gel method. And the composite surface area, morphology and structure were characterized by Brunauer-Emmett-Teller (BET) method, X-ray diffraction(XRD) and scanning electron microscopy (SEM). The results showed that BaF2 and TiO2 form a PN-like structure on the surface of the composite. Composites were used to catalyze the degradation of methyl orange by irradiation with ultraviolet light, γ-rays, and an electron beam(EB). It was demonstrated that the composite is found to be more efficient than prepared TiO2 and commercial P25 in the degradation of methyl orange under γ-irradiation. And increasing the composite catalyst concentration within a certain range can effectively improve the decolorization rate of the methyl orange solution. However, when the composite material is used to catalyze the degradation of organic matter in the presence of ultraviolet light or 10 MeV electron beam irradiation, the catalytic effect is poor or substantially ineffective. In addition, a hybrid mechanism is proposed; BaF2 absorbs γ-rays to generate radioluminescence(RL) and further excites TiO2 to generate photo-charges. And due to the heterojunction effect, the resulting photo-charge will produce more active particles. This seems to be a possible mechanism to explain γ-irradiation catalytic behavior.
Data from: Facile synthesis of NiCo2S4/CNTs nanocomposites for high-performance supercapacitors
Herein, porous NiCo2S4/CNTs nanocomposites were synthesized via a simple hydrothermal method followed by the sulfurization process using different sulfide sources. By comparing two different sulfur sources, the samples using thioacetamide as sulfide source delivered more remarkable electrochemical performance with a high specific capacitance of 1765 F/g at 1 A/g and an admirable cycling stability with capacitance retention of 71.7% at a high current density of 10 A/g after 5000 cycles in 2 M KOH aqueous electrolyte. Furthermore, an asymmetric supercapacitor (ASC) device was successfully fabricated with the NiCo2S4/CNTs electrode as the positive electrode and graphene as the negative electrode. The device provided a maximum energy density of 29.44 Wh/kg at a power density of 812 W/kg. Even at a high power density of 8006 W/kg, the energy density still reaches 16.68 Wh/kg. Moreover, the ASC presents 89.8% specific capacitance retention after 5000 cycles at 5 A/g. These results reveal its great potential for supercapacitors in electrochemical energy storage field.
Data from: Microbeam two-dimensional small-angle X-ray scattering investigating the effects of reduced graphene oxide on local microstructures of high-density polyethylene/reduced graphene oxide nanocomposite bars
It has reported that the introduction of reduced graphene oxide (RGO) can enhance the crystallization and orientation of high density polyethylene (HDPE) matrix and thus improve the mechanical properties of HDPE/RGO nanocomposites. Herein, the local microstructures and orientations in different regions of HDPE/RGO bars with varied RGO contents were further explored by two dimensional small angle X-ray scattering (2D SAXS) using a microbeam technique. It is unveiled that the orientation orderings of every positions are all intensified with increasing RGO amount, and of particular interest is the observation of the quite slight change of the ordering degrees in diverse zones of HDPE/RGO nanocomposite bars, implicating that RGO imposes a uniform enhancing effect upon HDPE matrix within different areas and consequently reflects an effective increase of mechanical properties of HDPE/RGO nanocomposites.
Data from: Enhanced virus filtration in hybrid membranes with MWCNT nanocomposite
Membrane separation is proved to be a powerful tool for several applications such as wastewater treatment or the elimination of various microorganisms from drinking water. In this study, the efficiency of inorganic composite based multi-walled carbon nanotube hybrid membranes was investigated in the removal of MS2 bacteriophages from contaminated water. With this object multi-walled carbon nanotubes were coated with copper(I) oxide, titanium(IV) oxide and iron(III) oxide nanoparticles, respectively, and their virus removal capability was tested in both batch and flow experiments. Considering the possible pH range of drinking water, the filtration tests were carried out at pH 5.0, 7.5 and 9.0 as well. The extent of MS2 removal strongly depended on the pH values for each composite, which can be due to electrostatic interactions between the membrane and the virus. The highest removal (≥99.99%) was obtained with the Cu2O-coated MWCNT water membrane in the whole pH range. The fabricated nanocomposites were characterized by X-ray diffraction, specific surface area measurement, dynamic light scattering, zeta potential measurement, Raman spectroscopy, transmission electron microscopy and scanning electron microscopy techniques. This study presents a simple route to design novel and effective nanocomposite-based hybrid membranes for virus removal.
