In the present work, we have reported the in situ oxidation of manganese (II) acetate to MnO2 nanoparticles through the thermal plasma carbonized natural hydroxyapatite (MnO2/TP-NHAp) as a neoteric sustainable method. Interestingly, the thermal plasma-processed surface of the NHAp shows a great ability for oxidation of the manganese (II) without need of any external oxidizing agents. The cataly...

The aldehyde-selective oxidation of alkenes bearing diverse oxygen groups in the allylic and homoallylic position was accomplished with a nitrite-modified Wacker oxidation. Readily available oxygenated alkenes were oxidized in up to 88% aldehyde yield and as high as 97% aldehyde selectivity. The aldehyde-selective oxidation enabled the rapid, enantioselective synthesis of an important pharmaceu...

Herein, graphene oxide is produced by electrochemical oxidation method from graphite rod to examine its hydrogen peroxide sensing ability. The electrochemically produced graphene oxide is characterized by SEM and XRD. A few layers of Graphene Oxide(GO) sheets and corrugations in graphene sheets appeared intensely crumpled and folded into a typical wrinkled structure after electrochemical oxidat...

The partial oxidation of methane to synthesis gas was investigated in a novel type of perm selective membrane reactor using Perowskite hollow fibers. The operating behaviour of this membrane reactor integrating the process steps selective separation of oxygen from air, selective O2 transfer in the membrane and oxidation of methane with simultaneous steam reforming was investigated theoretically...

Different sulfides were oxidized to the corresponding sulfoxides, which is useful in drug industriesand important in biological activities, with a novel magnetically separable catalyst consisting oftungstic acid supported on silica coated magnetic nanoparticles in water as a green solvent in a goodto excellent yield without any over oxidation to sulfones in a simple, selective, and eco-friendly...

This article addresses the fundamental question of whether concepts from semiconductor physics can be applied to describe the working mode of heterogeneous oxidation catalysts and whether they can be even used to discriminate between selective and unselective reaction pathways. Near-ambient-pressure X-ray photoelectron spectroscopy was applied to the oxidation of n-butane to maleic anhydride on...

Lanthanum modified Fe-ZSM-5 catalyst can both increase selective methane oxidation performance and decrease H 2 O consumption.
