Dimensionality Control of Electrocatalytic Activity in Perovskite Nickelates

Nano Letters, 2020
The dimensionality of the crystal structure plays an important role in the electronic structures of materials. Ruddlesden-Popper perovskite oxides offer an attractive platform for studying this role due to dimensional flexibility. The effects of dimensionality on physical properties in those oxides have been widely reported.

Surface geometry and electrocatalytic activity

Materials Chemistry and Physics, 1989
Abstract The theory of electrode reaction was completed some thirty years ago for the hydrogen evolution reaction of reaction type A plus A going to A 2 on pure metals whose surface is composed of single atomic species. However, that for the hydrogen evolution reaction on surfaces composed of two atomic species as well as that for reaction of the ...

Electrocatalytic Oxygen Evolution with an Immobilized TAML Activator

Journal of the American Chemical Society, 2014
Iron complexes of tetra-amido macrocyclic ligands are important members of the suite of oxidation catalysts known as TAML activators. TAML activators are known to be fast homogeneous water oxidation (WO) catalysts, producing oxygen in the presence of chemical oxidants, e.g., ceric ammonium nitrate.

Polyoxometalate-stabilized Pt nanoparticles and their electrocatalytic activities

Physical Chemistry Chemical Physics, 2011
The synthesis of long-term stable polyoxometalate (POM)-stabilized Pt nanoparticles (NPs) is described here. By means of controlled bulk electrolysis, the reduced POM anions, SiW(12)O(40)(4-) (or SiW(12)) and H(2)W(12)O(40)(6-) (or H(2)W(12)), respectively, served the dual role of reductant and protecting/stabilizing ligand for the Pt NPs. Transmission

Electrocatalytic activity of DNA on electrodes as an indication of hybridisation

Bioelectrochemistry, 2006
Electron transfer between metal electrodes and ferro/ferricyanide is completely suppressed at low ionic concentration. We describe here a new phenomenon related to this reaction: an immobilisation of thiolated single-stranded DNA on gold electrodes retains this activity at low ionic strength up to the level corresponding to the high ionic strength.

Electrocatalytic activity of core/shell magnetic nanocomposite

Analytical Biochemistry, 2014
Electrically active magnetic nanocomposites (EAMNCs), Au nanoparticles/self-doped polyaniline@Fe3O4 (AuNPs/SPAN@Fe3O4) with well-defined core/shell structure, were first synthesized by a simple method. The morphology and composition of the as-synthesized AuNPs/SPAN@Fe3O4 nanocomposite have been characterized by transmission electron microscopy (TEM ...

Regulation of Electrocatalytic Activity by Local Microstructure: Focusing on the Catalytic Active Zone

Chemistry – A European Journal, 2021
AbstractTraditional regulation methods of active sites have successfully optimized the performance of electrocatalysts, but seem unable to achieve further breakthrough in the catalytic activity. Unlike the conventional viewpoint of focusing on single active site, the concept of local microstructure active zone is more comprehensive and new methods to ...

Origin of Electrocatalytic Activity in Amorphous Nickel–Metalloid Electrodeposits

ACS Applied Materials & Interfaces, 2021
In transition metal-based alloys, the nonlinearity of the current at large cathodic potentials reduces the credibility of the linear Tafel slopes for the evaluation of electrocatalytic hydrogen activity. High-precision nonlinear fitting at low current densities describing the kinetics of electrochemical reactions due to charge transfer can overcome ...
