Characterization of graphene segregated on Ni

Yu Q., Lian J., Chen Y-P, Li H., Lian J., Pei S-S, University of Houston, US

We report a surface segregation approach to synthesize high quality graphenes on Ni under ambient pressure. Graphenes were segregated from Ni surfaces by carbon dissolving at high temperature and cooling down with various cooling rates. [...]

Formation of Ni/NiO core/shell nanostructures and their attachment on carbon nanotubes

Chopra N., Claypoole L., Bachas L.G., University of Alabama, US

We report a facile wet synthesis method coupled with microwave irradiation to successfully control the morphology of Ni/NiO core/shell nanoparticles. Furthermore, we report for the first time, microwave-based synthesis of hollow NiO nanostructures from Ni [...]

Synthesis and electrochemical characterization of sponge-like nickel nanoparticles

Ramírez-Meneses E., Domiguez-Crespo M.A., Dorantes-Rosales H., Torres-Huerta A.M., Montiel-Palma V., Hernández-Tapia G., Cicata - IPN Unidad Altamira, MX

Nickel exhibits a high initial electrocatalytic activity toward the HER. Enhancement of cathodic activity of nickel for electrolytic hydrogen evolution has been carried out by the formation of nanostructured nickel materials. In this respect, the [...]

Structure of Ni nanoparticles/TiO2 films prepared by sol-gel dip-coating

García-Murillo A., Ramírez-Meneses E., Ramírez-Salgado J., Sandoval-Robles B.G., Montiel-Palma V., Dorantes-Rosales H., Del Angel-Vicente P., Cicata - IPN Unidad Altamira, MX

Titania thin films were synthesized by sol-gel dip-coating method with metallic Ni nanoparticles from an organometallic precursor. Titania matrix and Ni nanoparticles were prepared separately. Titania precursor solution was prepared mixing titanium isopropoxide in isopropanol [...]
