The reaction occurring on electrooxidation of Ru(bpy)(3)(2+) (bpy = 2,2'-bipyridine) and tri-n-propylamine (TPrA) leads to the production light emission. accepted mechanism this widely used involves Ru(bpy)(3)(3+) a reduced species derived from free radical TPrA. However, does not account for many observed features reaction. A new route involving intermediacy TPrA cation radicals (TPrA(*+)) in generation was established, based results scanning electrochemical microscopy...

The electron-hole pair formation that occurs at the interface between a semiconductor and solution upon absorption of light leads to oxidation or reduction reactions species. principles such photodriven processes are described as well applications semiconductors in electrochemical cells particulate systems for carrying out heterogeneous photocatalysis photoelectrosynthesis.
The collisions of single platinum nanoparticles at an ultramicroelectrode were observed electrochemically by their characteristic current−time transients for a particle-catalyzed reaction. A event is characterized the current generated electrocatalyzed reaction indicator species (proton, hydrogen peroxide) present in solution. Since does not occur selected and can involve high concentration with much larger diffusion coefficient than nanoparticle, large amplification (10 orders magnitude or...

We propose guidelines for the design of improved bimetallic (and related) electrocatalysts oxygen reduction reaction (ORR) in acidic media. This guide is based on simple thermodynamic principles assuming a mechanism where one metal breaks oxygen-oxygen bond molecular O(2) and other acts to reduce resulting adsorbed atomic oxygen. Analysis Gibbs free energies these two reactions guides selection combinations metals that can produce alloy surfaces with enhanced activity ORR when compared...

Reaching the goal of economical photoelectrochemical (PEC) water splitting will likely require combination efficient solar absorbers with high activity electrocatalysts for hydrogen and oxygen evolution reactions (HER OER). Toward this goal, we synthesized an amorphous FeOOH (a-FeOOH) phase that has not previously been studied as OER catalyst. The a-FeOOH films show comparable to another cocatalyst, Co-borate (Co-Bi), in 1 M Na2CO3, reaching 10 mA/cm(2) at overpotential ∼550 mV nm thick...
