The issue with supporting life on these worlds beyond the temperature constraints, is the potential lack of oxidation-reduction chemistry, which is the basis of all life. Conor Feehly, Discover Magazine, 23 Oct. 2024 Word History First Known Use 1899, in the meaning defined above Time Travele...
Alper,H - 《Pure & Applied Chemistry》 被引量: 22发表: 1988年 Using of electronic processes at oxidation-reduction reactions on surface of semiconductor catalysts for electric energy generation A new method of conversion of chemical energy into electrical power is considered. For this it is used...
where the adsorption site of hydrogen is denoted by Asterisks. Note that Eqs. (2) and (3) are both electrochemical step. Based on the above reduction step, we can gain the rate equations along with the site conservation condition: $$\frac{{\theta }_{H*}}{\partial t}={k}_{1}{\th...
H2O2 can be generated in-situ from cathodic O2 reduction during ozonation, called as an E-peroxone process. Wang et al. [28] reported enhanced the kinetics and OH• yields from O3 decomposition in a water matrix that has high ozone stability than those with low stability. Authors found tha...

X-ray Diffraction (XRD) analysis was carried out using a PANalytical X’Pert3Powder X-ray powder diffractometer equipped with a Cu Kα radiation source, at a scan rate of 9 °/min, in Analytic Instrumentation Center of College of Chemistry and Molecular Engineering at Peking University. The...
摘要: The reaction of nitriles, containing a labile hydrogen, with copper salts at 70–150 proceeds as an oxidation-reduction reaction of one-electron transfer from the nitrile to Cu2+. A probable scheme of the process was proposed.DOI: 10.1007/BF00927484 年份: 1975 ...

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 organic compounds, which provides a light-induced ave...
The chemistry of rare-earth metals (Sc, Y and lanthanides) has been dominated by trivalent oxidation states, except for divalent europium, ytterbium, and samarium and tetravalent cerium. The lack of readily accessible oxidation states limits the participation of rare earth metals in redox chemistry....
