Transparent nanostructured NiO electrodes were prepd. by heating Ni(OH)2 sol-gel films at 300-320°. Nanostructured NiO (bunsenite) behaves as a p-type semiconductor and has an indirect band gap of 3.55 eV. It shows a strong anodic electrochromic effect, as ...
Recent progress made in our lab. in the field of electrochem. promotion of heterogeneous catalytic gas reactions is reviewed. The phenomenon consists of electrochem. polarization of the catalyst/solid electrolyte interface resulting in a dramatic, non-Fara ...
Electroceramics research is driven by technology and device applications. This growing field includes a vast number of magnetic, dielectric, ionically conducting, semiconducting, and superconducting ceramics used in domains as diverse as transportation, in ...
The anodic oxidn. of 2-naphthol in acid media was studied at a synthetic boron-doped diamond thin film electrode (BDD) using cyclic voltammetry and bulk electrolysis. The results showed that in the potential region, where the supporting electrolyte is stab ...
A review. Recent work on the charge transport in mesoscopic nanostructured film electrodes is summarized. Results from intensity-modulated photocurrent spectroscopy (IMPS) and intensity-modulated photovoltage spectroscopy (IMVS) studies are given, and the ...
An electrolytic cell assembly, e.g. for use in solar panels, is formed by placing coated metal wires between the conducting layers of two conducting glasses, resp. A pressure force is applied to press the metal wires between the conducting layers and to br ...
A method has been developed to study the mechanisms of the thiocyanato ligand exchange reactions between the redox couple I-/ I3- and the ruthenium complex bis(tetrabutylammonium) cis-bis(thiocyanato)bis(2,2'-bipyridine-4-carboxylic acid, 4'-carboxylate)ru ...
We present a study of the kinetics of electron injection in ruthenium(II) cis-(2,2‘-bipyridyl-4,4‘-dicarboxylate)2(NCS)2-sensitized nanocrystalline TiO2 films as a function of electrical potential applied to the TiO2 film and as a function of the compositi ...
A consortium was created to investigate electroceramic materials that show ionic or mixed ionic-electronic conduction (MIEC), for application as oxygen separation membranes and in solid oxide fuel cells (SOFC, electrolytes and cathodes). The focus is on de ...
In this work, the voltammetric charge and work function of Rh catalyst were studied to clarify the origin of electrochem. promotion. The measures were carried on at 375 Deg, either in a non-reactive oxygen/helium gas mixt. or under complete oxidn. of propy ...
