Surfactant-free preparation of supported cubic platinum nanoparticles.
نویسندگان
چکیده
A novel method has been developed for preparing supported cubic platinum nanoparticles. Carbon monoxide and hydrogen are used to reduce platinum precursors present at a solid-gas interface and to control the shape of the growing Pt nanoparticles. By avoiding the use of any organic agents in the synthesis, cubic Pt particles free of hydrocarbons are formed, thereby avoiding possible contamination of the catalyst surface. The approach used is simple and readily scalable.

متن کاملAmmonia-mediated Method for One-step and Surfactant-free Synthesis of Magnetite Nanoparticles
Magnetite (Fe3O4) nanoparticles have been successfully prepared by a novel one-step and surfactant-free approach utilizing ferrous ion, as a single iron source. In this manner, the reaction occurs between two aqueous solutions via the spontaneous transfer of ammonia gas from one to another in room temperature. No ferric source or oxidizing specie, oxidation controlling and capping agents are ne...
متن کاملPlatinum-Free Counter Electrode Comprised of Metal-Organic-Framework (MOF)-Derived Cobalt Sulfide Nanoparticles for Efficient Dye-Sensitized Solar Cells (DSSCs)
We fabricated a highly efficient (with a solar-to-electricity conversion efficiency (η) of 8.1%) Pt-free dye-sensitized solar cell (DSSC). The counter electrode was made of cobalt sulfide (CoS) nanoparticles synthesized via surfactant-assisted preparation of a metal organic framework, ZIF-67, with controllable particle sizes (50 to 320 nm) and subsequent oxidation and sulfide conversion. In con...
متن کاملSynthesis and characterization of the Pt/SiO2 nanocomposite by the sol-gel method
The silica supported platinum nanoparticles was synthesized by using the sol-gel method. The possibility of using diamminedinitro platinum (II) as Pt precursor and effect of metal precursor concentration on the final Pt nanoparticle size was investigated. A stable silica sol was prepared via hydrolysis of tetraethyl orthosilicate (TEOS) as a metal alcoxide and condensation reaction. Subsequentl...
متن کاملSynthesis of Bimetallic Platinum Nanoparticles for Biosensors
The use of magnetic nanomaterials in biosensing applications is growing as a consequence of their remarkable properties; but controlling the composition and shape of metallic nanoalloys is problematic when more than one precursor is required for wet chemistry synthesis. We have developed a successful simultaneous reduction method for preparation of near-spherical platinum-based nanoalloys conta...
