Process for producing Li4Ti5O12 and electrode materials

Nanostructured Li4Ti5O12 (spinel) was prepared via a method employing lithium ethoxide and Ti(IV) alkoxides as the starting reagents. The optimized materials contained less than 1% of anatase as the main impurity and, depending on the synthetic conditions, ...

Mesoporous network electrode for electrochemical cell

Michael Graetzel

A high kinetics rate electrochemical cell in which at least one of the electrodes is composed of a mesostructural electroactive material is comprising a three-dimensional framework structure of mesoporous texture forming a bicontinuous junction of large sp ...

The electroreduction of hydrogen on platinum(111) in acidic media

Nicola Marzari, Roberto Car

We propose a new mechanism for the electroreduction of hydrogen in acidic media. The specific model and theoretical calculations are designed for the Pt(111) surface, because this is the only face that exhibits a clear first order phase transition. The bas ...

Photoelectrochemistry of Nanostructured WO3 Thin Film Electrodes for Water Oxidation: Mechanism of Electron Transport

Ulf Anders Hagfeldt

Nanostructured WO3 thin films were prepd., and photooxidn. of water at such films was studied in a pH 4.68 soln. The cathodic current at potentials

Lithium intercalation in nanoporous anatase TiO2 studied with XPS

Ulf Anders Hagfeldt

Intercalation of lithium ions in nanoporous anatase TiO2 was studied with XPS using a novel electrochem. prepn. technique. The electrolyte was 0.5 M LiClO4 in acetonitrile (not water-free). The electrochem. insertion of lithium ions creates reduced Ti ions ...

Li+ ion insertion in TiO2 (anatase). 1. Chronoamperometry on CVD films and nanoporous films

Ulf Anders Hagfeldt

Electrochem. insertion of lithium in nanoporous and CVD samples of anatase was studied by chronoamperometry. The currents following cathodic and anodic potential steps were monitored as a function of film thickness, temp., and electrolyte concn. The time d ...

Effects of lithium intercalation on the electronic properties of FePS3 single crystals

Giorgio Margaritondo, Helmuth Berger

The reaction of FePS3 single crystals with a 1.6M n-butyl lithium solution in n-hexane has been followed through de electrical conductivity measurements as a function of the intercalation time. In order to investigate the influence of lithium insertion on ...
