© 2014 Materials Research Society MRS BULLETIN • VOLUME 39 • FEBRUARY 2014 • www.mrs.org/bulletin Introduction The development of (electro)catalytic materials has traditionally relied on the design of new compositions and structures. In principle, previously unseen and desirable properties can be obtained by perturbing the structure of existing materials with elastic strain. Uncovering the fund...

Unexpected yet highly remarkable and intriguing observations of the polymer-enhanced electro-catalytic activity of the Pt nanoparticles for electro-oxidations of both methanol and formic acid were reported. In situ FTIR investigation suggests strongly that the observed activity enhancements are highly likely due to the PVP-induced additional reaction pathways. These observations may open up a n...

in this study, undoped zno and doped with fe and mn nanostructures were synthesized by hydrothermal method. the morphology of nanostructures was characterized by scanning electron microscope. the electrochemical response of the carbon paste electrode modified with nanoparticles of zno and also zno doped with fe and mn toward levodopa (l-dopa) was studied. studies of cyclic voltammetry using pro...

Comparative (electro)catalytic, structural, and spectroscopic studies in hydrogen electro-oxidation, the (inverse) water-gas shift reaction, and methane conversion on two representative mixed ionic-electronic conducting perovskite-type materials La0.6Sr0.4FeO3-δ (LSF) and SrTi0.7Fe0.3O3-δ (STF) were performed with the aim of eventually correlating (electro)catalytic activity and associated stru...

Multi-Metal Oxide (Electro)catalysts Multi-metal oxide (MMO) nanomaterials have significant potential to facilitate various demanding (electro)catalytic reactions, but their intrinsic complexity hinders in-depth understanding of the origin catalytic activity. In article number 2107868, Kug-Seung Lee, Seoin Back, Yung-Eun Sung, Taeghwan Hyeon, and co-workers develop a structural uniform-sized sp...

In this article, PtAg alloy nanoislands/graphene hybrid composites were prepared based on the self-organization of Au@PtAg nanorods on graphene sheets. Graphite oxides (GO) were prepared and separated to individual sheets using Hummer's method. Graphene nano-sheets were prepared by chemical reduction with hydrazine. The prepared PtAg alloy nanomaterial and the hybrid composites with graphene we...

The review highlights recent advances and remaining challenges in single atom catalysts for thermal- electro-catalytic hydrogenation reactions.

A novel pentacoordinate mono iron dicarbonyl complex bearing a nitrogen heterocyclic carbene ligand was reported as a model of a [Fe]-hydrogenase active site, which exhibits interesting proton coupled CO binding reactivity, electro-catalytic proton reduction and catalytic transfer hydrogenation reactivity.

in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...
