2014年5月1日 · Is there a complete list of all the half equations for $\ce {H2O2}$ - both oxidation and reduction, in acidic and alkaline conditions? I've looked on the internet but can't seem to find a list with ...

2017年4月1日 · Hydrogen peroxide emerged as major redox metabolite operative in redox sensing, signaling and redox regulation. Generation, transport and capture of H 2 O 2 in biological settings as well as their biological consequences can now be addressed.

4 天之前 · Sonicated emulsive water microdroplets (SEWMs) accelerate and enable a variety of catalyst-free chemical transformations. However, significant unanswered questions remain regarding the chemical intermediates they form and their possible redox origin. In this study, we identified dissolved O2 as the primary originator of reactive oxygen species (ROS) such as OH• and H2O2. We uncovered the ...

Hydrogen peroxide (H 2 O 2) is an important metabolite involved in most of the redox metabolism reactions and processes of the cells. H 2 O 2 is recognized as one of the main molecules in the sensing, modulation and signaling of redox metabolism, and it is acting as a second messenger together with hydrogen sulfide (H 2 S) and nitric oxide (NO).

2024年4月18日 · In this work, we prepared ceria nanoparticles supported on carbon nanotube (CeO x /CNT) composite catalysts and investigated ceria’s promotional effect on the neutral 2e – ORR. The optimal CeO x /CNT catalyst demonstrated a 1.5-fold increase in ORR activity compared to CNT alone, with high H 2 O 2 selectivity over 87%.

2024年9月23日 · We begin with an overview of the key redox reactions involved in H 2 O 2 synthesis from oxygen and water, with brief summaries of how these reactions can be used in reactors powered by sunlight (i.e., photocatalysis), renewable electricity (electrocatalysis) or a combination of sunlight and electricity (photo-electrocatalysis).

2014年2月1日 · In this contribution, we report systematic studies on the redox reaction of hydrogen peroxide (H 2 O 2) and the H–D kinetic isotope effect on ORR on Au (100) in 0.1 M HClO 4. The correlation of reaction (1) to the high overpotential at the onset for ORR and the key factors that limit ORR kinetics on Au (100) in acidic electrolyte are discussed.

2014年11月24日 · A redox relay was identified in mammalian cells where the H2O2-reactive protein peroxiredoxin-2 oxidizes the transcription factor STAT3, resulting in the formation of transcriptionally inactive...

2020年9月25日 · Investigating biological redox reactions, I identified hydrogen peroxide (H 2 O 2) as a normal constituent of aerobic life in eukaryotic cells. This finding led to developments that recognized the essential role of H 2 O 2 in metabolic redox control.

2025年3月20日 · Here we demonstrate sustainable and unassisted electrochemical H2O2 production (via the two-electron oxygen reduction reaction) coupled to the oxidative valorization of glycerol, a biomass energy ...
