In recent years, electrocatalytic degradation of pollutants based on nanogenerators has gradually emerged. Compared with the huge energy consumption traditional electrocatalysis, this method can effectively use displacement current to induce charge transfer and complete catalysis, so it directly existing water flow other sources in nature. This work will explain basic principles, methods, measu...

Porous Pt nanowire arrays show enhanced electrocatalytic activities for ethanol oxidation in direct alcohol fuel cells.

The use of single crystal electrodes in electrocatalysis have allowed researchers to understand some of the elementary steps in different reactions and to establish some relationships between the activity of an electrocatalyst and its surface structure. But the precise identification of the particular type of crystallographic site on a nanoparticle sized electrocatalyst where the reaction takes...

The variation of the three-dimensional (3D) structure membrane electrode a fuel cell during proton exchange cycling involves corrosion/compaction carbon support. increasing degradation continuously reduces electrocatalytic performance cells (PEM-FCs). This phenomenon can be explained by performing 3D tomographic analysis at nanoscale. However, conventional approaches which present limited exper...

Pharmaceuticals are used every day in most parts of the world and great proportions these substances excreted unaltered or as active sub-products, posing a threat pollution. To protect aquatic ecosystems, innovative solutions such photocatalysis, electrocatalysis photoelectrocatalysis required. In this article we provide comprehensive review photo- electrocatalytic techniques for removal pharma...

the electrocatalysis of the oxygen reduction reaction (orr) on carbon supportedpt-v (1:1) catalyst in polymer electrolyte fuel cells (pefc) was investigated. atan oxygen pressure of one atm an enhanced electrocatalytic property of pt-v/ccompared with pt/c is revealed. these results indicate the occurrence of adifferent electrocatalytic mechanism for the orr on pt/c and pt-v/c. anincrease of mas...

Redox electrocatalysis (catalysis of electron-transfer reactions by floating conductive particles) is discussed from the point-of-view of Fermi level equilibration, and an overall theoretical framework is given. Examples of redox electrocatalysis in solution, in bipolar configuration, and at liquid-liquid interfaces are provided, highlighting that bipolar and liquid-liquid interfacial systems a...

It is shown that iron(II) tetra-aminophthalocyanine complex electropolymerized onto a multi-walled carbon nanotube-modified basal plane pyrolytic graphite electrode greatly enhanced the electrocatalytic detetion of amitrole (a toxic herbicide), resulting in a very low detection limit (0.5 nM) and excellent sensitivity of 8.80±0.44 μA/nM, compared to any known work reported so far. The electroca...

Cubic PtCu nanocages (NCs) were successfully synthesized through a redox reaction using cuprous oxide (Cu2O) as a sacrificial template and reducing agent. The porous PtCu NCs were composed of amounts of PtCu nanograins with an average particle size of 2.9 nm. The electrocatalytic performance of the PtCu NC electrode towards H2O2 was studied by cyclic voltammetry (CV) and chronoamperometry. The ...
