Nanocatalysts for Electrocatalytic Oxidation of Ethanol
ChemSusChem, 2019AbstractThe use of ethanol as a fuel in direct alcohol fuel cells depends not only on its ease of production from renewable sources, but also on overcoming the challenges of storage and transportation. In an ethanol‐based fuel cell, highly active electrocatalysts are required to break the C−C bond in ethanol for its complete oxidation at lower ...

Efficient electrocatalytic formic acid oxidation over PdAu-manganese oxide/carbon
Journal of Colloid and Interface Science, 2021Developing high efficient Palladium-metal-based electrocatalysts is of great significance for formic acid oxidation (FAO) reaction. Here, we experimentally synthesize PdAu alloy composited with MnOx electrocatalyst (PdAu-MnOx/C) and illustrate its remarkable FAO performance.

Amorphous NiFe Oxide‐based Nanoreactors for Efficient Electrocatalytic Water Oxidation
Angewandte Chemie International Edition, 2023AbstractSynergy engineering is an important way to enhance the kinetic activity of oxygen‐evolution‐reaction (OER) electrocatalysts. Here, we fabricated NiFe amorphous nanoreactor (NiFe‐ANR) oxide as OER electrocatalysts via a mild self‐catalytic reaction. Firstly, the amorphousness helps transform NiFe‐ANR into highly active hydroxyhydroxides, and its

(Invited) Electrocatalytic Ammonia Oxidation
ECS Meeting Abstracts, 2020Much 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, 2014AbstractThis 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
2008Hydrogen (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, 2011A 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).

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 ...
