The valence state of thallium affecting its toxicity, distribution and mobility, photoxidation reaction of Tl(I) was studied under the radiation from high-pressure arc mercury light or solar light. The results show that the low pH, the strong light intensity and UVB and VUC region are in ...
O-O bond formation is a key elementary step of the water oxidation reaction. However, it is still unclear how the mechanism of O-O coupling depends on the applied electrode potential. Herein, using water-in-salt electrolytes, we systematically altered the water activity, which enabled us to p...
In this work, we report that light-induced oxidative half-reaction of water splitting is effectively integrated with the reductive coupling of aryl bromides in the presence of the activated Pd/g-C3N4(named as Pd/g-C3N4*) and Na2CO3, which provides a method for using green water as the red...
Chemistry on water is a fascinating area of research. The surface of water and the interfaces between water and air or hydro-phobic media represent asymmetric environments with unique properties that lead to unexpected solvation effects on chemi-cal and photochemical processes. Indeed, the features of...
Reaction enthalpies for the hydrolysis of 3p, 4p and early 3d oxide bridges – how unique are the oligophosphates? Chem. Phys. Lett. 348, 433–439 (2001). Article Google Scholar Lindgren, M. et al. Toward a comprehensive mechanistic understanding of hydrogen uptake in zirconium alloys by ...
The ozonation combined with UV-radiation (O3/UV) is an efficient catalytic system for the degradation of refractory pollutants in wastewater. The process is initiated by the photolysis of ozone and followed by the production of OH• radicals by the reaction of O• with water [19]. The syn...
NHE and the formation of H2O2 by removal of two electrons is subjected to a barrier of 1.776 V vs. NHE [1]. The most extensively studied reaction is the four-electron oxidation of two water molecules producing molecular oxygen and four protons:2H2O → O2 + 4e− + 4H+ This reaction is...
Reaction barriers of the hydrogen transfer of H2O2 are an average of 10 kcal/mol or higher than the reaction barriers of the oxidation of DMS. Therefore, a two-step oxidation mechanism in which, first, the transfer of a hydrogen atom occurs to form water oxide and, second, the transfer ...
Such a model has been previously used to describe the kinetics of reactions at semiconductor interfaces, with a first-order dependence on the hole density4,5,6. In our work, we demonstrate that in multielectron redox processes, such as water oxidation, the order of the reaction can deviate ...
The electro-oxidation of water to oxygen is expected to play a major role in the development of future electrochemical energy conversion and storage technologies. However, the slow rate of the oxygen evolution reaction remains a key challenge that requires fundamental understanding to facilitate the de...
