The laws governing the oxidation of hydrogen over platinum apply also to palladium and other noble metals, and this fact makes it probable that the mechanism is the same in each case. Some stages of the mechanism that we have analyzed are probably to be found also in the case of the non...
The oxidation number of fluorine in all its compounds is –1 5) The oxidation number of other halogens in their compounds is usually –1 2 Oxidation Numbers: Rules 6) The oxidation number of hydrogen is +1 when it is combined with more electronegative elements (most nonmetals) and –1 wh...
In recent years chemistry has become a central science for its recognized potential to solving both the upcoming energy crisis and the problem of anthropogenic CO2 emissions. Whether a future sustainable world will be based on hydrogen or carbon-based fuels, the reduction of either protons or CO2...
Moreover, the heterogeneous oxidation of pyrimidine-thioether 203, with hydrogen peroxide, in [C2mim][BF4] at 40°C was also performed. Reaction proceeded over mesoporous Ti/Ge catalyst, affording selectively the corresponding sulfoxide 204 in 77% yield and 95% conversion (Entry 2, Scheme 82) ...
Surface degradation phenomena of two model equiatomic alloys from the CrMnFeCoNi alloy system were investigated in 2% O2 and 10% H2O (pO2 = 0.0

with a high peak power density of 577 mW cm−2(18 times as high as the Ni/C anode) and a stability of more than 150 h (a degradation rate slower by 7 times than the Ni/C anode). The spectroscopies demonstrate that the alloy effect from Cu weakens the hydrogen binding, and...

The common oxidizing agents are ozone, hydrogen peroxide, hypochlorites, chlorine, and chlorine dioxide. Chemical oxidation depends on the client the oxidizing agents and the chemical contaminants. Chemical oxidation is also a part of the treatment process for cyanide-bearing and metals such as ...
Many nano catalysts containing Mn or Co were prepared for the oxidation of toluene, and permanganate was used for the oxidation of toluene as early as 1975 [41]. The ability of permanganate to abstract a hydrogen atom is rationalized on the basis of the strong O-H bond formed on H· addi...
