A bipolar filter press-type elec. rechargeable Zn/O2 battery has been developed. Reticulated copper foam served as substrate for the zinc deposit on the anodic side, and La0.6Ca0.4CoO3-catalyzed bifunctional oxygen electrodes were used on the cathodic side ...
Nanostructured anatase TiO2 electrodes surface modified with inorg. metal oxide clusters, i.e., phosphotungstic acid (PWA), was studied by XPS and spectroelectrochem. The surface modifiers were electroactive and could be addressed reversibly by changing th ...
The photoelectrochem. behaviors of dye-sensitized nanoporous TiO2 solar cells are studied under influences of light intensity, redox couple concn., temp., different cations and water in the nonaq. soln. The value of the ideality factor of dyed nanoporous T ...
The use of ZrO2 membrane on counter electrodes (e.g. Zr) is proposed for controlling the mass transfer rates to the electrode and therefore the extent of possible loss reactions. A comparative study was undertaken to examine the influence of the prepn. tec ...
Photoelectrochem. measurements have been performed on film electrodes consisting of linked nano-sized TiO2 colloids. The film thickness ranged from 1-40 μm. The film network was attached to a thin transparent conducting layer of SnO2 allowing for photogene ...
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3 (perovskite) catalyzed bifunctional oxygen electrodes and 3-D zinc electrodes were prepd. and tested in a bipolar zinc/air battery. In addn., a numerical model for the zinc electrode wa ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in monopolar zinc/air cells. In addn., a bipolar Zn/air stack was tested using re ...
A complete system for cleavage of water by light (250‐W lamp) comprises the catalysts Pt and RuO2 and the sensitizer Ru(bpy) as well as the acceptor methylviologen (MV2+). 150 ml of solution gave 0.6 ml of H2 and 0.3 ml of O2 in h. ...
