Identifying the Activation Mechanism and Boosting Electrocatalytic Activity of Layered Perovskite Ruthenate

Small, 2020
AbstractSrRuO3 as a rare conductive perovskite ruthenate has attracted increasing attention for application in energy conversion. Here, the electrocatalytic activity for the hydrogen evolution reaction (HER) of thermally synthesized layered SrRuO3 is investigated and shows a considerable activation during cathodic polarization in alkaline solution.

Synthesis and electrocatalytic activities of Co3O4 nanocubes

Journal of Nanoparticle Research, 2010
In this article, a hydrothermal method was developed to synthesize Co3O4 nanocubes using hydrogen peroxide (H2O2) as oxidant, Co(NO3)2·6H2O as a cobalt source. The products are characterized in detail by multiform techniques including X-ray diffraction (XRD), energy dispersive X-ray analysis (EDS), scanning electron microscopy (SEM), and transmission ...

Electrocatalytic activity of self-doped polyaniline

Electrochimica Acta, 2012
Self-doped conducting polyaniline-modified indium tin oxide (ITO) electrodes were prepared by cyclic voltammetry on ITO substrates in aniline (AN) and o-aminobenzene sulfonic acid (OSA) mixed monomer solutions with AN/OSA mole ratios of 25/75, 50/50, and 75/25, followed by investigations on electrocatalytic activities of the copolymers to redox ...

Prediction of electrocatalytic activity of boron nanostructures

Chemical Physics Letters, 2018
Abstract The dissociation of O2 and HO2 are important reactions that occur at the cathode of fuel cells producing H2O and use platinum as a catalyst. There is a need to replace platinum with less expensive catalysts. Here the possibility of boron nanostructures as catalysts for the reactions is considered using density functional theory.

Enhancement of electrocatalytic activity of gold nanoparticles by sonochemical treatment

Chemical Communications, 2010
We demonstrate that gold nanoparticles can become catalytically active for the electrochemical hydrogen oxidation reaction by a sonication treatment. Experimental data and theoretical calculations indicate that the activity arises from the supercooled molten state of gold nanoparticles which are enriched with coordinatively unsaturated gold atoms.

Electrocatalytic Activity of Nitrogen-Doped Carbon Nanotube Cups

Journal of the American Chemical Society, 2009
The electrochemical activity of stacked nitrogen-doped carbon nanotube cups (NCNCs) has been explored in comparison to commercial Pt-decorated carbon nanotubes. The nanocup catalyst has demonstrated comparable performance to that of Pt catalyst in oxygen reduction reaction.

Synthesis, Characterization and Electrocatalytic Activity of Fused Gold Nanoparticles

Journal of Nanoscience and Nanotechnology, 2011
This paper describes the synthesis of fused spherical gold nanoparticles (AuNPs) and their electrocatalytic activity towards the oxidation of hydroxylamine (HA). Fused AuNPs were prepared by one-pot synthesis using 2-mercapto-4-methyl-5-thiazoleacetic acid (TAA) as a stabilizing agent and sodium borohydride (NaBH4) as a reducing agent.

Synthesis of Atomic Gold Clusters with Strong Electrocatalytic Activities

Langmuir, 2008
Small atomic gold clusters in solution, Au n , stabilized by tetrabutyl ammonium bromide (TBABr), have been synthesized by a simple electrochemical technique, based on the anodic dissolution of a gold electrode in the presence of TBABr salt, and using acetronitrile as solvent.
