It was also observed that the absorption of UVC (UV with wavelength between 200 and 280 nm) is responsible for the dissociation of H2O2 to generate the reactive hydroxyl radicals. Depending on the initial dosages, the H2O2 added to the system can be completely decomposed by UV within 50 to...

Following, the continuous oxidation of cyanide from Cu(CN)2 and the attendant dissociation of Cu(CN)2 led to progressive liberation of Cu+. Transformation of Cu+ to Cu2+ was confirmed afterward by X-ray photoelectron spectroscopy analysis. Meantime, the OH signal was detected by electron spin...
adsorption and H2O dissociation of 10-Bi2O3/Ta2O5 results in efficient OOH formation.10-Bi2O3/Ta2O5 exhibits excellent durability for 80 h at 0.4 VRHE.Over 90% FE during H2O2 produce in homemade H-cell.The applications of on-site production of low-concentration H2O2 in water ...
(1 0 1), which were regarded as the primary crystal facets of H2O2interacting with PMGA. Therefore, the contribution of these two facets to the H2O2activation ability was compared using DFT calculations, and the H2O2dissociation process was explored. As shown inFig. 6a, H2O2molecules only ...
3), which suggests the dissociation of OOH* intermediate or re-adsorption of hydrogen peroxide by the adjacent Co atoms (less than 4 Å) for the further reduction to water is less likely7. Electron energy loss spectroscopy (EELS) analysis (Fig. 1e) of an area within Fig. 1d further...

(6) At the same time, dissociation equilibria of the organic compound itself and of the various intermediates formed, such as hydroxyl, hydroperoxide radicals, etc., according to the following: H2O2 → HO−2 + H+, (7) HO·2 → H+ + O−2 . (8) Like other phenolic compounds, ...
The top 10 precursor ions were selected in the MS scan by the Orbitrap with a resolution r = 60,000 for fragmentation in the linear ion trap using collision-induced dissociation. Normalised collision-induced dissociation was set at 35.0 and spectra were submitted to a local MASCOT (Matrix ...
(i) the increased number of cavitation bubbles [23], (ii) the shortened ultrasound wave periods and increased bubble surface-to-volume ratio (S/V) leading to enhanced rectified diffusion [2], [24], and (iii) the higher intrabubble vibronic temperatures providing higher dissociation degree of ...
