Dispersed stabilized Pt nanoparticles synthesized from an organometallic precursor

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

In electrocatalysis, carbon materials have been generally employed to support metallic nanoparticles for electrochemical applications. Many methods to prepare CNTs supported metal nanoparticles including electrochemical, microwave irradiation and wet chemical methods have been reported in [...]

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 [...]
