Electrocatalytic water oxidation occurs on high surface area, nanocrystalline ITO (nanoITO) surface-derivatized by phosphonate-binding of the catalyst [Ru(Mebimpy)(4,4'-((HO)(2)OPCH(2))(2)bpy)(OH(2))](2+) (Mebimpy is 2,6-bis(1-methylbenzimidazol-2-yl)pyridine; bpy is 2,2'-bipyridine). With nanoITO, spectral data can be acquired on electrochemically generated intermediates and voltammograms moni...

The inner tubes of carbon nanotubes (CNTs) have a significant promotion effect on the electrocatalytic activity of Pd nanoparticles (NPs) for the ethanol oxidation of direct alcohol fuel cells (DAFCs) and Pd NPs supported on CNTs with 3-7 walls show a much higher activity as compared to that supported on typical single-walled and multi-walled CNTs.

We report on a versatile approach for preparing on-substrate, self-standing and hollow-wall nanotubes (NTs) of Pt and PtRu-alloys. The method takes advantage of wet chemically processed ZnO-NTs that are used as sacrificial templates for electrodeposition. The electrocatalytic activity of these Pt-based NTs is exemplary demonstrated on the electro-oxidation of methanol.

A new electrochemical strategy for the simple and ultrasensitive evaluation of DNA methyltransferase (MTase) activity was developed based on electrocatalytic oxidation of ascorbic acid by graphene. In addition, the suitability of this sensing platform for MTase inhibitor screening was also demonstrated.

A facile recipe has been developed to prepare three-dimensional nanoarchitectures of nitrogen-doped graphene loading Co nanoparticle hybrids (Co/NG). The hybrids show an outstanding electrocatalytic activity for glucose oxidation reaction (GOR) and oxygen reduction reaction (ORR), and thus can be used as electrode materials of a nonenzymatic and precious-metal-free glucose fuel cell (GFC).

We report a solution phase synthesis of monodispersed mesoporous Pd nanoparticles (MPNs) with narrow particle size distributions. The average particle sizes can be controlled to a range of 25 nm to 42 nm, by utilizing cationic surfactants (as structure-directing agents) and triblock copolymers (as protective agents for controlled Pd deposition). The obtained MPNs exhibit very high electrocataly...

Partially unzipped carbon nanotubes prepared by strong oxidation and thermal expansion of carbon nanotubes were explored as an advanced catalyst support for PEM fuel cells. The unique hybrid structure of 1D nanotube and 2D double-side graphene resulted in an outstanding electrocatalytic performance.

Hollow PdCu alloyed nanocubes were successfully synthesized by a novel one-pot template-free strategy through tuning the surface energy difference of the crystal planes by alloying. Compared with the solid nanoparticles, the hollow nanocubes exhibit superior electrocatalytic activity and stability for formic acid oxidation.

Heat treatment of graphene oxide (GO) with ammonia flow at various temperatures resulted in different distribution of nitrogen species. Synchrotron based X-ray absorption near-edge structure (XANES) spectroscopy provides unambiguous evidence for the presence of three nitrogen species. The Pt/NG-800 composite exhibits outstanding electrocatalytic activity for methanol oxidation.

Let the light shine through: A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodepostion of Ni or Co onto the surface of the nanowires. These core-shell nanowire networks exhibit electrocatalytic performance equivalent to metal oxide films of similar composition, but are several times more transparent.
