Steering the Selectivity of Electrocatalytic Glucose Oxidation by the Pt Oxidation State

Angewandte Chemie - International Edition, 2023
AbstractElectrocatalytic glucose oxidation can produce high value chemicals, but selectivity needs to be improved. Here we elucidate the role of the Pt oxidation state on the activity and selectivity of electrocatalytic oxidation of glucose with a new analytical approach, using high‐pressure liquid chromatography and high‐pressure anion exchange ...

Perovskite Oxide as A New Platform for Efficient Electrocatalytic Nitrogen Oxidation

Angewandte Chemie, 2023
AbstractElectrocatalytic nitrogen oxidation reaction (NOR) offers an efficient and sustainable approach for conversion of widespread nitrogen (N2) into high‐value‐added nitrate (NO3−) under mild conditions, representing a promising alternative to the traditional approach that involves harsh Haber–Bosch and Ostwald oxidation processes.

Electrocatalytic oxidation of cyanide on copper-doped cobalt oxide electrodes [PDF]

Applied Catalysis B: Environmental, 2017
[EN] Copper and copper oxides are well-known excellent catalysts in several chemical processes, but their low mechanical and electrochemical stability restrict their direct utilization as electrodes in electrolytic processes. In this work, the incorporation of copper into cobalt oxide (CuxCo3-xO4) is presented as an excellent approach to obtain highly ...

Free radicals promote electrocatalytic nitrogen oxidation

Chemical Science, 2023
In this work, we introduce hydroxyl radicals into the electrocatalytic nitrogen oxidation reaction (NOR) for the first time. Co3O4+ ˙OH shows an excellent NOR performance among Co3O4catalysts in 0.1 M Na2SO4solution.

Switching on electrocatalytic activity in solid oxide cells [PDF]

Nature, 2016
Solid oxide cells (SOCs) can operate with high efficiency in two ways-as fuel cells, oxidizing a fuel to produce electricity, and as electrolysis cells, electrolysing water to produce hydrogen and oxygen gases. Ideally, SOCs should perform well, be durable and be inexpensive, but there are often competitive tensions, meaning that, for example ...

Electrocatalytic water oxidation with manganese phosphates

Nature Communications
AbstractAs inspired by the Mn4CaO5 oxygen evolution center in nature, Mn-based electrocatalysts have received overwhelming attention for water oxidation. However, the understanding of the detailed reaction mechanism has been a long-standing problem. Herein, homologous KMnPO4 and KMnPO4•H2O with 4-coordinated and 6-coordinated Mn centers, respectively ...

Electrocatalytic Ammonia Oxidation by a Low Coordinate Copper Complex

Journal of the American Chemical Society, 2022
Molecular catalysts for ammonia oxidation to dinitrogen represent enabling components to utilize ammonia as a fuel and/or source of hydrogen. Ammonia oxidation requires not only the breaking of multiple strong N-H bonds but also controlled N-N bond formation.

Electrocatalytic Oxidation of Guanine, Guanosine, and Guanosine Monophosphate [PDF]

Biophysical Journal, 2007
The electrochemical behavior of guanine, guanosine, and guanosine monophosphate (GMP) at redox polymer film modified indium tin oxide electrodes is examined by voltammetry and redox titration. Utilizing the redox polymer-coated electrodes as indicator electrodes, a new method for measuring the oxidation potentials, based on monitoring their catalytic ...

Electrocatalytic Ammonia Oxidation by Pyridyl-Substituted Ferrocenes

Journal of the American Chemical Society
Ammonia (NH3) is a promising carbon-free fuel when prepared from sustainable resources. First-row transition metal electrocatalysts for ammonia oxidation are an enabling technology for sustainable energy production. We describe electrocatalytic ammonia oxidation using robust molecular complexes based on Earth-abundant iron.
