A synergistic effect resulting from the interaction of small (2.4–3.1 nm) naked Pt nanoparticles (NPs) imprinted on N‐doped carbon supports is evidenced by structural, electronic and electrochemical characterization. The size and distribution of the sputtered Pt NPs are found to be related to the nature of the support because Pt NPs are preferentially located at Ngraphitic sites. In addition, Rutherford...
Herein, we report the total chemical synthesis of graphene assembled at a liquid–liquid interface through a chemical reaction starting from benzene as a monomer. The reaction occurs at the benzene/water liquid interface, taking advantage of the insoluble material (the growing graphene structures) assembling as a film, which allows a heterogeneous reaction with the precipitated material and a molecular...
This work describes a green route to multifunctional nanocomposite materials composed of natural rubber (NR) latex and graphene (rGO) or graphene oxide (GO). Aqueous solutions with different concentrations of GO and rGO (prepared with the surfactant cetyltrimethylammonium bromide – CTAB) were mixed with natural rubber latex under magnetic stirring followed by sonication. The slurries obtained after...
This work describes the synthesis, characterization and study of properties of novel multifunctional composite materials obtained by natural-rubber latex and a special kind of multi-walled carbon nanotube (CNT), in which the cavities are filled by magnetic species. To prepare stable aqueous dispersions of CNTs, two approaches have been employed, based on a mixture of the surfactant sodium dodecyl...
