(Invited) Electrocatalytic Ammonia Oxidation

ECS Meeting Abstracts, 2020
Much of the global effort toward producing solar fuels has involved splitting water to obtain molecular hydrogen. Unfortunately, hydrogen gas has a relatively low energy-per-volume, and extreme cryogenic temperature and pressure is needed to bring hydrogen to a condensed state.

Selective Glycerol Oxidation by Electrocatalytic Dehydrogenation

ChemSusChem, 2014
AbstractThis study demonstrates that an electrochemical dehydrogenation process can be used to oxidize glycerol to glyceraldehyde and glyceric acid even without using stoichiometric chemical oxidants. A glyceric acid selectivity of 87.0 % at 91.8 % glycerol conversion was obtained in an electrocatalytic batch reactor. A continuous‐flow electrocatalytic

Electrocatalytic H2 Oxidation Reaction

2008
Hydrogen (H2), an important material and product in chemical industries, has been investigated as a new clean energy source for many decades [1–3]. With the rapid development of proton exchange membrane (PEM) fuel cell technology, in which H2 is used as a fuel, the chemical energy stored in this H2 can be electrochemically converted to electric energy ...

Carbohydrates electrocatalytic oxidation using CNT–NiCo-oxide modified electrodes

Talanta, 2011
A new sensor for an amplified electrochemical detection of carbohydrates is proposed, where carbohydrates are oxidized by CNT-NiCo-oxide composite in basic solutions. Cyclic voltammograms of the modified electrode show a stable and well defined redox couple in alkaline media due to the synergy of Ni(II)/Ni(III) system with Co(II)/Co(III).

Electrocatalytical oxidation of arsenite by reduced graphene oxide via in-situ electrocatalytic generation of H2O2

Environmental Pollution, 2019
Preoxidation of As(III) to As(V) is required for the efficient removal of total arsenic in the treatment of wastewater. In this work, the electro-Fenton oxidation of As(III) with a high efficiency was successfully achieved by using the system of the stainless steel net (SSN) coating with reduced graphene oxide (RGO@SSN) as the cathode and stainless ...

Nickel Oxide Nanoclusters for Electrocatalytic Water Oxidation

ECS Meeting Abstracts, 2015
The growth and/or deposition of uniformly dispersed nanoclusters is a significant challenge for the field of electrocatalysis science. Here we employ ALD technique to obtain ultrafine nickel oxide nanoclusters uniformly dispersed on flat electrodes. Atomic layer deposition (ALD) is a versatile technique to the precise growth of a variety of materials ...

Electrocatalytic Methane Oxidation Greatly Promoted by Chlorine Intermediates

Angewandte Chemie International Edition, 2021
AbstractRenewable energy‐powered methane (CH4) conversion at ambient conditions is an attractive but highly challenging field. Due to the highly inert character of CH4, the selective cleavage of its first C−H bond without over‐oxidation is essential for transforming CH4 into value‐added products.

Electrocatalytic Oxidation of DNA-Wrapped Carbon Nanotubes

Journal of the American Chemical Society, 2005
The electrical properties of single-walled carbon nanotubes (CNT) are of intense interest due to applications in nanoelectronics. Cyclic voltammetry and chronoamperometry have been used to explore the Ru(bpy)32+ electrocatalytic oxidation of DNA-solubilized carbon nanotubes.

Mesoporous tin oxide for electrocatalytic CO2 reduction

Journal of Colloid and Interface Science, 2018
The increasing accumulation of CO2 in the atmosphere has been leading to serious environmental problems. Electrochemical reduction of CO2 is a potential means of carbon recycling for energy storage and environmental sustainability. However, it is limited by the lack of highly active and selective electrocatalysts. Here we demonstrate the development of

Electrocatalytic oxidation of nucleobases by TiO2 nanobelts

Physical Chemistry Chemical Physics, 2011
Two kinds of TiO(2) nanobelts were prepared from commercial P-25 powders via an alkaline hydrothermal method with and without an acid etching process. The uncauterized nanobelts (TNs) exhibited a smooth surface, and mixed phases of anatase and TiO(2) (B), whereas the cauterized ones (CTNs) displayed a rough surface and a pure anatase structure. TNs and
