| 1 | Effect of TiO_2 nanoparticles on hydrogen evolution reaction activity of Ni coatings显示文摘The electrocatalytic activity of electrodeposited Ni and Ni–TiO_2 coatings with regard to the alkaline hydrogen evolution reaction(HER) was investigated. The Ni coatings were electrodeposited from an acid chloride bath at different current densities, and their HER activities were examined in a 1.0-mol·L^(-1) KOH medium. The variations in the HER activity of the Ni coatings with changes in surface morphology and composition were examined via the electrochemical dissolution and incorporation of nanoparticles. Electrochemical analysis methods were used to monitor the HER activity of the test electrodes; this activity was confirmed via the quantification of gases that evolved during the analysis. The obtained results demonstrated that the Ni–TiO_2 nanocomposite test electrode exhibited maximum activity toward the alkaline HER. The surface appearance, composition, and the phase structure of all developed coatings were analyzed using scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS), and X-ray diffraction(XRD), respectively. The improvement in the electrocatalytic activity of Ni–TiO_2 nanocomposite coating toward HER was attributed to the variation in surface morphology and increased number of active sites. | Revanna Kullaiah Liju Elias Ampar Chitharanjan Hegde | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，4： | 5 |
| 2 | Microwave mediated synthesis and characterization of CeO_2-GO hybrid composite for removal of chromium ions and its antibacterial efficiency显示文摘A facile fabrication and processing of cerium oxide-graphene oxide(CeO_2-GO) hybrid nanocomposites without the use of any surfactant or any organic solvents using chemical method and treatment with microwave irradiation technique are reported. In-situ hexagonal nano cerium oxide particles embedded on the layered surface of GO sheets were investigated for the photodegradation of dyes, removal of chromium Cr(VI) ions and against antibacterial studies. The results imply that hybrid nanocomposites shows enhanced 5-folds of photocatalytic activities in UV(ultraviolet) light irradiation and exhibited rapid efficiency in the elimination of chromium ion better than the pure GO and CeO_2, which are inhibited by competent photosensitive electron inoculation and controlling the electron–hole recombination. The synergetic effect of CeO_2-GO composites played a vital role in showing better results against model bacterium than GO and CeO_2 are due to higher physical interaction endorsed to the stress of membranes acute by piercing edges,large surface area, and higher adsorptive conditions of graphene oxide sheets tailored with ceria particles. The amount of charge transferred at the interface increases with the concentration of O atoms, demonstrating the interaction between CeO_2 and GO is much stronger than CeO_2 and GO are due to the decrease of the average equilibrium distance between the interfaces. The CeO_2-GO interface staggered band alignments existing between the CeO_2 surfaces and GO which shows an excellent synergism. The structure and morphology of composites were tested by X-ray diffraction(XRD), Fourier transform infrared(FTIR), Raman, X-ray photoelectron spectroscopy(XPS), and high-resolution transmission electron microscope(HR-TEM). | Lellala Kashinath Keerthiraj Namratha Kullaiah Byrappa | 2019 | Journal of Environmental Sciences2019，31，2： | 3 |
