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...
Between the electrode and this boundary layer of ions exists, therefore, a certain difference of potential. If the distilled water is now replaced by a normal solution of a soluble zinc salt, such as zinc sulfate, the reaction is driven to the left and a new equilibrium established betwee...
characterization and catalytic reaction experiments. Q.H. performed some catalytic reaction experiments. Z.D. and M.D. performed the DFT calculations. S.D.K. and R.S. measured the XAFS spectra. C.T. measured the HAADF-STEM images of Mn-NG. J.G., C.L. and Z.D. analysed the data ...
The utilization of readily available and non-toxic water by photocatalytic water splitting is highly attractive in green chemistry. Herein we report that light-induced oxidative half-reaction of water splitting is effectively coupled with reduction of or
3). Chemical oxidation is a chemical reaction between oxidants and carbon materials to achieve an oxidation modification of the carbon material, thereby introducing oxygen-containing functional groups [32,33]. Depending on the oxidation conditions, chemical oxidation can be divided into liquid-phase ...
Oxidation-reduction potential (ORP) is a measurement that determines water’s oxidizing or reducing potential, quantifying a solution’s electron transfer capacity. ORP is valuable for assessing the presence of oxidizing or reducing agents, such as oxyge

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 ...
4) has been the main focus of the water oxidation research15,16,17,18,19,20,21,22,23,24,25,26,27,28,29 and less attention has been paid to the selective two-electron oxidation reaction of water to H2O2 (Eq. 1), which is considered as a much more difficult process. A main ...
