Animesh Dutta, in Journal of Energy Storage, 2020 2.1.1 Chemical oxidation Chemical oxidation is generally used when more hydrophilic biochar is desired. This process is performed in the presence of oxidants (e.g HCl, HNO3, H2O2, H3PO4) to increase oxygen functionalities. Some electrochemically...
For the inactive Au/TiO2 catalyst, the Au(I)–Au(III) redox couple cannot be constructed in the presence of oxidizing gas (NO, N2O, and NO2), which is thermally desorbed from the catalyst synthesis when aqua regia is used. Surprisingly, the inactive Au/TiO2 can be activated when it ...
Nitric oxide (NO) has important functions in biology and atmospheric chemistry as a toxin, signaling molecule, ozone depleting agent and the precursor of the greenhouse gas nitrous oxide (N2O). Although NO is a potent oxidant, and was available on Earth earlier than oxygen, it is unclear wheth...

The addition of NO to the flame (up to 400 ppmv) had no impact on mercury oxidation by chlorine or bromine. The addition of SO2 had no effect on mercury oxidation by chlorine at SO2 concentrations below about 400 ppmv; some increase in mercury oxidation... 展开 ...
Interestingly, after liquid-phase protonation-assisted exfoliation of Aza-CMP in 37% HCl18, ICP–OES analysis results showed that the synthesized Aza-CMP-Co (exfoliated) accommodated tenfold higher Co2+ loading (19.2 wt%) than that of untreated Aza-CMP-Co. Considering that two cobalt atoms...
The influence of various acidic gases including SO2, SO3, NH3, NOx, HCl, Cl-2, etc. have been discussed as well. We expect this work will shed light on the development of heterogeneous catalytic oxidation of elemental mercury technology in flue gases, particularly the synthesis of novel and...
of-function variants in OXR1 were reported to be associated with cerebellar atrophy. However, the impact of OXR1 on cellular functions and molecular mechanisms in the human brain is largely unknown. Notably, no human disease models are available to explore the pathological impact of OXR1 ...
reported the chemoselective sulfur oxygenation of various phosphoroamidates, thionophosphates, and thiophosphates using perfluorinated oxaziridine 80 (Equation 6; Table 7) <1995T7981>. Treatment of sulfide 126 with 1 equiv of oxaziridine 80 gave the corresponding sulfoxide in >98% yield, and with ...
