Levulinic acid (LA), 4-oxo-pentanoic acid, is a new platform chemical with various potential uses. In this paper, catalytic hydrogenation and oxidation of levulinic acid were studied. It was shown from experiments that levulinic acid can be hydrogenated to γ-valerolactone (GVL) over transition metal catalysts and oxidative-decarboxylated to 2-butanone (methyl-ethyl-ketone, MEK) and methyl-vinyl...

The persistence of recalcitrant pollutants in water is a major health issue calling for advanced and green techniques to clean polluted waters. For instance, direct activation peroxydisulfate by visible light without any catalyst displays remarkable potential degrade water, the involved reactive species pure conditions with deionized have been elucidated recently. However, impact phosphates, wh...

In this work, a novel pseudo triple-enzyme cascade catalysis amplification strategy was employed to fabricate a highly sensitive electrochemiluminescence (ECL) aptasensor for thrombin (TB) detection. The signal amplification of the proposed aptasensor was based on the synergistic catalysis of glucose dehydrogenase (GDH) and hemin/G-quadruplex to generate a co-reactant in situ for the ECL of per...

1,4-bis(triphenyl phosphonium)butane peroxodisulfate(BTPPBPDS) were synthesized by treating 1,4-bis(triphenyl phosphonium)butane dibromide and potassium peroxydisulfate in aqueous solution.This was used mild and efficient reagent for oxidation of alkyl benzenes to their corresponding carbonyl compounds in very good to high yields.

oxidation of methyl orange (mo) solution in potassium peroxydisulfate (kps) homogeneous reaction system without uv irradiation was investigated. the result shows that decolorization of mo increases as the dosage of k2s2o8 increases. the kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of mo is below 10 mg/l and langmuir–hinshew...
