Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater
Advanced Materials, EarlyView.Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

Advanced Materials, EarlyView.Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Separation‐Controlled Redox Reactions
Angewandte Chemie International Edition, 2021Abstract In the era of molecular devices and nanotechnology, precise control over electron‐transfer processes is strongly desired. However, redox reactions are usually characterized by reaction equilibrium constants strongly departing from unity.

Antioxidants & Redox Signaling, 2004
Redox reactions of hemoglobin have gained importance because of the general interest of the role of oxidative stress in diseases and the possible role of red blood cells in oxidative stress. Although electron paramagnetic resonance (EPR) is extremely valuable in studying hemoglobin redox reactions it has not been adequately used.

Electronegativity and redox reactions
Physical Chemistry Chemical Physics, 2016Using the maximum hardness principle, we show that the oxidation potential of a molecule increases as its electronegativity increases and also increases as its electronegativity in its oxidized state increases.

Redox reactions involve the change of oxidation state of a compound, caused by the transfer of oxygen and/or electrons between compounds; this is the core of most chemical reactions. This chapter introduces the basic concepts of redox reactions in organic chemistry before discussing the sustainability issues around redox reactions. The various types of

Talanta, 1967
In a study of redox reactions on columns, the work of Cerrai and Testa has been extended. It has been shown that insolubility of the redox compound is the most important factor and that adsorptive forces play little or no part. A useful redox column method for the determination of iron and vanadium, which compares favourably with that using a Jones ...

This chapter looks into redox reactions: oxidation, and reduction. Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons. The oxidation number of an element is the number of electrons that need to be added to the element needed to make a neutral atom.

Biochemical reaction engineering for redox reactions
The Chemical Record, 2004AbstractRedox reactions are still a challenge for biochemical engineers. A personal view for the development of this field is given. Cofactor regeneration was an obstacle for quite some time. The first technical breakthrough was achieved with the system formate/formate dehydrogenase for the regeneration of NADH2. In cases where the same enzyme could be

Ruthenium Nanocatalysis on Redox Reactions
Journal of Nanoscience and Nanotechnology, 2013Nanoparticles have generated intense interest over the past 20 years due to their high potential applications in different areas such as catalysis, sensors, nanoscale electronics, fuel and solar cells and optoelectronics. As the large fractions of metal atoms are exposed to the surface, the use of metal nanoparticles as nanocatalysts allows mild ...
