Water Interaction with Iron Oxides

Angewandte Chemie International Edition, 2015
AbstractWe present a mechanistic study on the interaction of water with a well‐defined model Fe3O4(111) surface that was investigated by a combination of direct calorimetric measurements of adsorption energies, infrared vibrational spectroscopy, and calculations bases on density functional theory (DFT).

Fast Water Oxidation Using Iron

Journal of the American Chemical Society, 2010
Photolysis of water, a long-studied strategy for storing solar energy, involves two half-reactions: the reduction of protons to dihydrogen and the oxidation of water to dioxygen. Proton reduction is well-understood, with catalysts achieving quantum yields of 34% when driven by visible light.

Oxidations and reductions in water

1998
Oxidation of organic compounds has probably been the most widely investigated process because it is of interest to both academic scientists and industrial technicians. Many oxidants and catalysts are known and a number of reaction conditions have been carefully investigated [1], The modern chemical industry requires selective highly efficient ...

Single-Site, Catalytic Water Oxidation on Oxide Surfaces

Journal of the American Chemical Society, 2009
Electrocatalytic water oxidation occurs through the use of the phosphonate-derivatized single-site catalyst [Ru(Mebimpy)(4,4'-((HO)(2)OPCH(2))(2)bpy)(OH(2))](2+) [Mebimpy = 2,6-bis(1-methylbenzimidazol-2-yl)pyridine; bpy = 2,2'-bipyridine] at pH 1 and 5 on fluorine-doped SnO(2) or Sn(IV)-doped In(2)O(3) electrodes or on nanocrystalline TiO(2).

Cosputtered Calcium Manganese Oxide Electrodes for Water Oxidation

Inorganic Chemistry, 2017
Calcium manganese oxide films were prepared by cosputter deposition from Mn and CaMnO3 targets and evaluated for their suitability as catalysts for the oxygen evolution reaction (OER). Scanning electron microscopy (SEM) revealed a compact morphology for the as-deposited films and the formation of nanorodlike features on the surfaces after annealing at ...

Greenlighting Photoelectrochemical Oxidation of Water by Iron Oxide

ACS Nano, 2014
Hematite (α-Fe2O3) is one of just a few candidate electrode materials that possess all of the following photocatalyst-essential properties for scalable application to water oxidation: excellent stability, earth-abundance, suitability positive valence-band-edge energy, and significant visible light absorptivity.

The Ru−Hbpp Water Oxidation Catalyst

Journal of the American Chemical Society, 2009
A thorough characterization of the Ru-Hbpp (in,in-{[Ru(II)(trpy)(H(2)O)](2)(mu-bpp)}(3+) (trpy is 2,2':6',2''-terpyridine, bpp is bis(2-pyridyl)-3,5-pyrazolate)) water oxidation catalyst has been carried out employing structural (single crystal X-ray), spectroscopic (UV-vis and NMR), kinetic, and electrochemical (cyclic voltammetry) analyses.

Nitrous Oxide Emissions from Waste Water

Environmental Monitoring and Assessment, 1994
The estimation of nitrous oxide emissions is complicated by the high degree of uncertainty on the emission factors involved and by the limited acquaintance with all significant nitrous oxide sources. A potentially important source for which emission data are lacking is the sewage system transporting waste water from human activities.
