[159] observed that the degradation of pharmaceuticals present in hospital wastewater was comparatively low for the O3/H2O2 process as compared to ozonation alone so the addition of hydrogen peroxide along with the ozone for the removal of pharmaceuticals is not efficient as compared to the ozone ...
Probe sampling followed by on-line FTIR analyses and off-line GC-TCD/FID analyses were used to measure the concentration profiles of the reactants, stable intermediates and the final products. The addition of hydrogen in variable concentrations significantly increases the reactivity of the natural ...
A digestion mixture suitable for the decomposition of soil and plant materials is described. This is based on sulphuric acid and hydrogen peroxide as oxidants with the addition of lithium sulphate to elevate the digestion temperature and selenium as catalyst. The subsequent solution is suitable for ...
It has been shown that photocatalytic reactions are enhanced by utilisation of alternative electron acceptors. We report here enhanced photocatalytic degradation of microcystin-LR following the addition of hydrogen peroxide to the system. It was also found that hydrogen peroxide with UV illumination alone...
At the levels of O 2 (200 μM) and H 2O 2 (0.1 μM) in surface sea waters, the oxygen oxidation is 130 times faster than peroxide oxidation. In rainwaters, however, the concentration of hydrogen peroxide (100 μM) is great enough so that H 2O 2 is the dominant oxidant for Cu...
is of considerable interest for converting the intermittent electricity generated by renewable energy sources into storable chemical energy, but the typical water electrolysis process requires a high working voltage (>1.23 V) and produces oxygen at the anode in addition to hydrogen at the cathode....
The hydrogen binding energy (HBE), which represents the binding strength of the HOR intermediates to the catalysts, is considered the primary activity descriptor for the HOR catalysts39. In alkaline conditions, the condition is more complex, and 2 ~ 3 orders of magnitude lower kinetics are ...
aWhen, in addition to the heat for the reaction, the heat duty for preheating the reactants is also covered by the oxidation of oxygenate, then the amount of hydrogen produced via reforming is drastically reduced. 当,除热之外为反应,热义务为预先加热反应剂由氧化作用也包括时氧化,然后被生产的猛...
Furthermore, the nanolubricant with 0.01 wt% concentration of MoS2 nanoparticle showed an enhancement of 61.15% in oxidation induction time in comparison to the base oil. Furthermore, MoS2 addition within the base oil demonstrates a ~ 10% improvement in thermal conductivity compared to the ...
Oxidation of renewable polyol/sugar into formic acid using molecular O2 over heterogeneous catalysts is still challenging due to the insufficient activation of both O2 and organic substrates on coordination-saturated metal oxides. In this study, we devel
