Selenite and selenocystamine [(CyaSe)2] efficiently activate the decomposition of H2O2 by GSH and by other thiols, as demonstrated using a leuco crystal violet POD-based H2O2 assay which is applicable (unlike other assays) also in presence of thiols. The GPx-like activities were estimated to be 3.6 and 2.7 mumol H2O2/min per mumol SeO3(2-) and (CyaSe)2, respectively. Both selenium compounds als...

M in ne ap ol is , M N 5 54 47 VAPORIZED PERACETIC ACID (VPA) STERILIZATION Peracetic Acid as a Biocide REVOXTM sterilization technology uses a room temperature vapor composed of three active compounds; hydrogen peroxide (H2O2), acetic acid and peracetic acid (PAA). PAA is formed by the reaction of acetic acid and H2O2 with the addition of a catalyst; these compounds exist in equilibrium and th...

The synthesis of adipic acid, which is formed by the reaction cyclohexene oxidized hydrogen peroxide (H2O2), hazardous because highly exothermic nature this and H2O2 decomposition. objective comprehensive study was to investigate illustrate effects sulfuric acid (H2SO4) stabilizer (EDTA) on thermal hazard decomposition green also provided a reference reduce risk reactions. Various calorimetry t...

The catalytic performances of titanium species in TS-1 zeolite for the hydroxylamine formation have been investigated using the density functional theory with the ONIOM scheme. The reaction process for making hydroxylamine is divided into two steps: (i) the H2O2 decomposition over the Ti species to produce the peroxo titanium species and (ii) the NH3 oxidation over the generated oxidizing speci...

Laboratory-made snow doped with either hydrogen peroxide (H2O2) or formaldehyde (HCHO) was exposed to radiation in the UV and visible range resulting in a decomposition of both compounds. These experiments demonstrate that besides the photolysis of nitrate further photochemical reactions of atmospheric relevant compounds can take place in snow. Under similar conditions the decomposition of H2O2...

Carbon-based metal-free catalyst has attracted more and more attention. It is a big challenge to improve catalytic activity of metal-free catalyst for decomposition of H2O2 to produce hydroxyl radical (HO•). Here, we report chloro-benquinone (TCBQ) modified on graphene oxide (GO) as metal-free catalyst for strong promotion of HO•. By the incorporation of GO, the HO• production by H2O2 and TCBQ ...

Introduction One-pot oxidation reaction consisted of direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 gases and oxidation reaction using in situ generated H2O2 is promising synthetic method, because it is possible to use the unstable H2O2 immediately without isolation/purification steps, which would contribute to energy and time saving as well as avoid the risk of transportation of t...
