An activated catalyst for the rapid decomposition of HOis provided wherein a porous high surface area catalyst base, e.g. a zeolite molecular sieve (ZMS) is impregnated or doped with a solution of metal cation salts and an ionic promoter, dried and calcined to form an activated catalyst. ...
Direct reduction of H2O2, H2O2 decomposition, O2 reduction, and O2 desorption are predicted as the reactions involved in the HPRR while O2 reduction and O2 desorption are negligible at low and high overpotentials, respectively. Investigation of the effect of the electrolyte and catalyst loading ...
To elucidate the O2reduction pathway for H2O2production, we devised a continuous “Light-Ar/Dark-O2” experiment similar to plant photosynthesis (Fig.4a)39. The system was purged with Ar gas to exhaust O2gas in the pure water before turning on the light. Approximately 129 μM H2O2was gene...
It has been found that the GO-TCBQ with ability to catalyze the decomposition of H2O2, generating HO•. Thus, GO-TCBQ can be used for H2O2 detection or wound disinfection. Conclusion In summary, a Janus effect of gentle metal-free catalysis facilitated production of hydroxyl radical and...
42 For Ni-based steam reforming catalysts, it is assumed that coke formation starts as a result of hydrocarbon decomposition on the catalyst surface resulting in Cα. This coke species can be either gasified or polymerized to more stable Cβ, which may form carbidic surface carbon compounds.50...

Ti O2-doped Fe3O4 NPs catalyzed the decomposition of H2O2 to oxidize methylene blue without external energy supply, resulting in effective decoloration. Ti O2-doped Fe3O4 NPs showed high catalytic activity under various p H values and even in the presence of radical scavenger. More catalysts ...
of H2O2 decomposition were carried out to ascertain that thesupport alone does not decompose H2O2.We used pure calcinedsulfated ceria at 20 °C,1 bar for 5 h.14Reactor Setup for the Experiments.A cocurrent,downflowTBR was developed.In addition to the motivations alreadymentioned,the TBR ...
Here, we first report the reactivity of natural magnetites with a variety of elemental impurities for catalyzing the decomposition of H2O2 to produce hydroxyl free radicals (•OH) and the consequent degradation of p-nitrophenol (p-NP). We observed that these natural magnetites show higher ...
in Fenton-like AOP system, however, addition of irradiation (photo-Fenton-like system) improved efficiency of Cu/MnKIL-2 (Mn/Si = 0.01, Mn/Cu = 0.06) for 10 % if compared to MnKIL-2 (Mn/Si=0.01) due to the additional OH radicals produced by the decomposition of H2O2 by the light...
