J.G. performed synthesis, 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...
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...
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...
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 ...
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 ...
Abstract Wet air oxidation of phenol has been studied in a 2 1 reactor through which both gas and liquid phases flow continuously. The reactor was used as a stirred cell with a flat gas liquid interface. Reaction temperatures were between 230 and 280°C. Phenol conversions between 80% and ...

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 ...
