Recently, sulfur (S)-vacancies created on the basal plane of 2H-molybdenum disulfide (MoS2) using argon plasma exposure exhibited higher intrinsic activity for the electrochemical hydrogen evolution reaction than the edge sites and metallic 1T-phase of MoS2 catalysts. However, a more industrially viable alternative to the argon plasma desulfurization process is needed. In this work, we introduc...

Reducing environmental pollution via elimination of sulfur compounds from gas condensate was the aim of this research. Whereby oxidative desulfurization from gas condensate with 3200 ppm initial sulfur was accomplished by hydrogen peroxide (30%wt) as oxidant and formic acid as catalyst. The sulfones after generation in the oxidation step were extracted through a method of liquid-liquid extracti...

Dibenzothiophene (DBT) is oxidized to the corresponding sulfoxide and sulfone in an emulsion system (W/O) composed of polyoxometalate anion [C(18)H(37)N(CH(3))3](5)[PV(2)Mo(10)O(40)] as both the surfactant and catalyst, using molecular oxygen as the oxidant and aldehyde as the sacrificial agent under mild conditions.

Abstract A novel CuWO 4 /SiO 2 heterojunction catalyst was successfully synthesized using a new sulfonamide derivative. The physical characteristics of the prepared samples were investigated by TGA, XRD, FTIR, SEM, UV, PL, and XPS. catalysts applied as nano photocatalyst for photooxidative desulfurization dibenzothiophene under visible light hydrogen peroxide an oxidant. photocatalytic oxidativ...

In the process of desulfurization, will produce a lot of the desulfurization liquid, desulphurization waste liquid containing high concentrations of salt, has the very good use value. If direct emissions will not only damage to the environment, but also wastes resources The reduction of the pollution resulting from desulfurization was studied. Rotary evaporator was employed to simulate vacuum c...

Tumor Necrosis Factor alpha (TNFα) is an inflammatory cytokine that plays a central role in the pathogenesis of chronic inflammatory disease. Here we describe the chemical synthesis of l-TNFα along with the mirror-image d-protein for use as a phage display target. The synthetic strategy utilized native chemical ligation and desulfurization to unite three peptide segments, followed by oxidative ...
