Hydrogen Evolution from Metal Nanoparticles Synthesized in a Deep Eutectic Solvent
نویسندگان
چکیده
In the present work, Pd, Rh and PdRh nanoparticles (NPs) were synthesized in a deep eutectic solvent (DES) by electrodeposition onto glassy carbon substrate. The NPs evaluated for hydrogen evolution reaction (HER, Hydrogen Evolution Reaction), an acid medium. results showed that highest catalytic activity HER was metallic Rh.

متن کاملPrussian blue nanospheres synthesized in deep eutectic solvents.
A novel route for controlled synthesis of Prussian blue nanospheres (PB NSs) with different sizes by using deep eutectic solvents (DES) as both solvent and template provider was demonstrated. The size-controlled PB NSs were obtained directly by the coordination of Fe(CN)(6)(4-) ion with Fe(3+) ion in the DES. The probable mechanism of formation of PB NSs was discussed based on the characterizat...
متن کاملSelf-assembly of gold nanoparticles on deep eutectic solvent (DES) surfaces.
Self-assembly of gold nanoparticles was obtained by sputter deposition on DES. SAXS and TEM investigations reveal the formation of spherical nanoparticles with a mean diameter of 5 ± 0.5 nm. For extended sputtering times, the number density of AuNPs increases linearly and a very pronounced 1st and 2nd shell ordering is observed.
متن کاملCopper Electrodeposition from a Water-Containing Choline Chloride Based Deep Eutectic Solvent
This study investigated the effect of water on the physical and electrochemical properties of a choline chloride deep eutectic solvent (DES). Physical and electrochemical measurements were performed on the DES containing varying amounts of water. When the water content was increased from 1% to 15 wt%, the viscosity and density declined while the conductivity increased significantly. Similarly, ...
