Here, we report hydrogen peroxide generation at 2-nitrophenyloctyl ether (NPOE)-water interface with decamethylferrocene as an electron donor. The progress of this reaction was detected by the observation of color change of the organic and aqueous phases i ...

Gold Nanofilm Redox Catalysis for Oxygen Reduction at Soft Interfaces

Hubert Girault, Pekka Eero Peljo, Micheal Diarmaid Scanlon, Evgeny Smirnov

Functionalization of a soft or liquid-liquid interface by a one gold nanoparticle thick “nanofilm” provides a conductive pathway to facilitate interfacial electron transfer from a lipophilic electron donor to a hydrophilic electron acceptor in a process kn ...

Targeted design of alpha-MnO2 based catalysts for oxygen reduction

Michael Markus Busch

The paper focuses on theoretical and experimental aspects of an oxide surface optimization for oxygen reduction reaction (ORR). Various doped alpha-MnO2 based electrocatalysts were prepared by microwave-assisted hydrothermal synthesis and electrochemically ...

Pergamon-Elsevier Science Ltd2016

H2O2 is produced at the interface between a room-temperature ionic liquid with decamethylferrocene as electron donor and an acidic aqueous solution. The electron donor can be regenerated electrochemically. ...

Two-Dimensional Metal-Organic Networks as a New Class of Electrocatalysts

Benjamin Wurster

This thesis deals with the electrocatalytic properties of two-dimensional metal organic coordination networks (2D-MOCNs) self-assembled on electrode surfaces and catalytic activity of 2D-MOCNs is demonstrated for the first time. The low-coordinated metal c ...

A Fast and Selective Near-Infrared Fluorescent Sensor for Multicolor Imaging of Biological Nitroxyl (HNO)

Pablo Rivera Fuentes

The first near-IR fluorescent turn-on sensor for the detection of nitroxyl (HNO), the one-electron reduced form of nitric oxide (NO), is reported. The new copper-based probe, CuDHX1, contains a dihydroxanthene (DHX) fluorophore and a cyclam deriv. as a Cu( ...

Reactions of ferrate(VI) during water treatment generate perferryl(V) or ferryl(IV) as primary intermediates. To better understand the fate of perferryl(V) or ferryl(IV) during ferrate(VI) oxidation, this study investigates the kinetics, products, and mech ...
