متن کاملPorphyrin hybrid complex ([2Fe-2S]2TPPS) as a catalyst for determination of hydrogen peroxide.
A new promising mimetic enzyme, a [2Fe-2S] cluster-porphyrin hybrid complex ([2Fe-2S]2TPPS), has been synthesized and applied to the determination of hydrogen peroxide. Under the optimum condition, the calibration graph has a linear range of 8.0 x 10(-8) - 1.0 x 10(6) mol/l H2O2 with a detection limit (3sigma, N = 9) of 5.3 x 10(-9) mol/l.
متن کاملGraphene/Hemin Hybrid Material as a Catalyst for Degradation of Alkaline Lignin with Hydrogen Peroxide
A graphene/hemin (H-GN) catalyst for lignin degradation was prepared by a wetchemistry method with graphene oxide and hemin. Hemin was absorbed onto the graphene surface through π-π interaction. Graphene served as a supporting material for hemin, providing a large contact area between the active molecules of catalyst and substrate, as well as protecting hemin from self-oxidation and maintaining...
متن کاملSulfric acid as Effective Catalyst for the Oxidation of 2-Methyl Naphthalene by hydrogen peroxide
The oxidation of 2-Methylnaphthalene (2-MN) was carried out in actic acid with 30%H2O2. 2-Methyl-1,4Naphthoquinone (2-MNQ) was obtained in a yield of 81.3% when sulfric acid used as catalyst. The aromatic substituted pathway is speculated as the dominated oxidation pathway with a higher conversion than the epoxidation one due to the activity of CH3CO3H2 + formed by actic acid and H+ supplied fr...
متن کاملA chiral iron-sexipyridine complex as a catalyst for alkene epoxidation with hydrogen peroxide.
A chiral iron-sexipyridine complex-hydrogen peroxide mixture is a highly efficient catalytic system for styrene epoxidation with excellent reactivity (3 min, 95% yield) and chemoselectivity (98%).
