A novel approach is presented towards the preparation of arrays of one-dimensional platinum nanoparticles catalysts. This method provides facetted surfaces with two low-index surfaces, (111) and (100), connected by edges in nanoscale proximity, which resembles much, closely the realistic nanoparticle.

The activity of three different arrays containing different ratios of (111) and (100) strontium titanate substrates for an oxygen-reduction reaction is evaluated, which is considered to be the most important reaction for fuel cells. The studies have shown that the surface area (100) facets are one of the major factors governing catalyst performance in the electrochemical reduction of oxygen molecules.

A novel, platinum-based electrocatalysts is developed for the CO electrooxidation reaction in CO(g)-saturated solution. The studies have shown that highly undercoordinated atoms on the adislands are responsible for the remarkable activity of these materials.

The article focuses on a study which investigated the effect of solid oxide fuel cell (SOFC) electrode crystal structure and morphology on its electrochemical performance and the electrochemical and thermal behavior of electrodes. Findings suggested that the bias and time dependent changes in the concentration and in the electronic state of the A-site element of the perovskite at the top air-electrode film interlace can improve the electrochemical performance of the electrode under DC current.
