When the heat of adsorption is the same on different metals the O(1s) binding energy is also the same. It is suggested that π bonding (back donation) is the major contribution to the M-CO bond. Correlation of the binding energy with the heat of adsorption suggests that, at 295 K, ...
The process, as written, is endothermic (energy must be provided to make it proceed);conversionof ozone back into diatomic oxygen is promoted by the presence of transition metals or their oxides. Pure oxygen is partly transformed into ozone by a silent electrical discharge; the reaction is also...
Energy (light) may also activate oxygen, generating the so-called singlet oxygen forms. All these reactive oxygen forms are called “ROS.” In the lay press these forms are regularly indicated as oxygen radicals. This is not correct because not all of these intermediate oxygen species contain ...
Hydrodeoxygenation (HDO), one of the effective approaches of C鈥揙 bond scission, plays a crucial role in biomass-derived oxygenate conversion to high value-added chemicals and biofuels. Herein, we systematically investigated the HDO reaction of furfural (FAL) to 2-methylfuran (2-MF) over 17 ...
This work was supported in part by the Toyota Research Institute through the Accelerated Materials Design and Discovery programme and the Skoltech-MIT Center for Electrochemical Energy. We thank Professor Zhong-Qun Tian from Xiamen University for fruitful discussion. This work used the Extreme Science...
This dynamic process is driven by the projectile energy, a large fraction of which is carried away by the product molecule. Despite the implied similarity, the ER reaction process is different from sputtering (physical ejection of surface matter): a targeted new bond is formed, typically at ...
摘要: A displacement threshold at 310 keV has been observed by electrical measurements in single crystal ZnO and has been identified as the minimum electron energy required for oxygen displacements by observing the production of F - centers above this threshold with EPR....
A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM). Data were acquired by a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), equipped ...
From a macroscopic view, the heat released by hydrogen combustion can be used as energy. From a molecular view, the reactions include several steps: breaking of the H–H and O–O bonds and formation of the H–O bond. Electron transfer also occurs in this process. Because of the picosecond...
and the improvement effect on the combustion process is very significant. Oxygen-enriched combustion technology has a great application prospect for energy saving and emission reduction. Therefore, it is necessary to study the burning velocity and emission characteristics of NH3under the oxygen-enriched ...
