The objective is to elucidate catalyst design and associated reaction mechanisms, as well as the relationship between catalyst structure and activity, in order to provide an insight for producing H2O2in an efficient, highly selective, and stable manner.Nonferrous Metals Society of ChinaRare MetalsDan-...
2, the solar exposure of 10 ppm of CMS (equivalent to a theoretical Fe2+ of 1 ppm; 10 ppm of CMS in an acidic solution was determined to contain 1 ppm soluble Fe) enhanced the E. coli inactivation efficiency obtained by SODIS treatment, reaching total inactivation in 30 min less than ...
Without any other organic solvents or halide present, direct catalytic oxidation of cyclohexene to adipic acid with hydrogen peroxide catalysed by Na2WO4.2H2O and acidic ionic liquids has been performed with excellent yields and selectivities, and the catalyst system could be easily reused....

Na2WO4·2 H2O (1 mmol) was dissolved in 50 mL deionized water termed solution B, which added x mL (CH3COO)2Mn (0.1 M) and y mg graphene oxide (GO) under vigorous stirring. Then, solutions A and B were magnetically stirred for 0.5 h. Subsequently, the prepared ...
Finally, different termination reactions take place through radical recombination reactions: HO· + HO· → H2O2, (3) (4) HO· + HO·2 → H2O + O2, (5) HO·2+ HO·2 → H2O2+ O2. (6) At the same time, dissociation equilibria of the organic compound itself and of the various ...
Clean synthesis of adipic acid by direct oxidation of cyclohexene with H202 catalyzed by Na2WO4 · 2H2O and acidic ionic liquid[ J]. Journal of Chemi- cal Research ,2005,164:520 - 522.Gui JZ, Liu D, Cong XH, Zhang XT, Jiang H, Hu ZD, Sun ZL (2005) Clean synthesis of adipic ...
In the Fe0/H2O2 process, under acidic conditions and as a result of the dissolution processes, the metallic iron becomes a Fe2+ ion source. Fe2+ ions undergo oxidation to Fe3+ in the presence of H2O2, while H2O2 undergoes conversion to HO• and OH−. Reactions 1–5 allow for ...
hydroxyl radical in acidic medium. In addition, the competitive reactions to H2O2 photo-reduction such as the consumption of hydroxyl radicals by the protons, the dismutation of hydrogen peroxide and the duplication of hydroxyl radicals are negligible under these conditions. This indicated that the ...
The reactions involved in this process are the following [7]: Fe2+ + H2O2 → Fe3+ + •OH + OH− (1) Fe3+ + H2O + hν → Fe2+ + •OH + H+ (2) The two oxidation-reduction reactions occur repeatedly until complete mineralization of the organic pollutants to CO2 and H2O is...
