In this study, highly ordered anodic porous metal oxides of transition metals (W, Fe, Co, and Nb) were prepared by anodization combined with a pretexturing process. The formation of an array of dimples on the metal surface was achieved by dry etching

The use of copper single-crystal electrodes (CSCEs) has revealed the crucial role of electrode structure in electrocatalysis and corrosion. CSCEs, although commercially available, can be prepared in-house by melting the end of a Cu wire to form a sin

A new class of Prussian blue analogs, Na2NixCo1 − xFe(CN)6 (0 ≤ x ≤ 1) with various nickel-to-cobalt ratios (from pure nickel to pure cobalt with a 10% increase in Co content for each sample) was prepared and tested as cathode materials for sod

Some general considerations pertaining to electrochemical water oxidation at transition metal oxide films are outlined. It is suggested that hydrated surfaquo groups are key species in the oxygen evolution reaction mechanism. The latter connect homog

Sulfonated Diels Alder poly(phenylene) (SDAPP) was examined for vanadium redox flow battery (VRFB) use. The ion exchange capacity (IEC) was varied from 1.4, 1.6 and 2.0 meq/g in order to tune the proton conductivity and vanadium permeability. Coulomb

The use of solvents with very high dielectric permittivity like propylene carbonate (PC) or ethylene carbonate (EC) appears to be the basis of the electro-catalytic reduction of 1,3-dibromopropane (DB3) at metallic interfaces, in particular at common

The electrochemical reduction of oxygen on cubic Pd nanoparticles (PdNPs) was studied in acid solution using the rotating disk electrode (RDE) method. The electrocatalytic properties of Pd nanocubes were compared with those of spherical PdNPs and bul

The application of shape-controlled Pt nanoparticles is rapidly increasing mainly because surface reactivity is, for many cases, structure sensitive. Shape control is generally obtained by using capping agents which finally cover the surface. However

Carbon-supported Pt nanoparticles have been prepared by a borohydride reduction method in a mixed water–ethylene glycol (EG) solvent with different EG content XEG. The synthesis in the mixed solvent modifies (1) the size and morphology of nanoparti
