Effective silica supported Sb–V mixed oxide catalyst for selective oxidatio…
Abstract. Silica supported Sb–V mixed oxide catalysts (VSbOx/SiO2) were prepared and evaluated in methanol selective oxidation. One-pass yield of formaldehyde at 91% was obtained on one VSbOx/SiO2 catalyst. The active phase of VSbOx/SiO2 catalysts is found to be Sb–V mixed oxide, in which isolated VOx species can be stabilized. The relative amount of monomeric VOx species in VSbOx/SiO2 …

Direct splitting of H2S into H2 and S on CdS-based photocatalyst under visibl…
Abstract. The conversion of H2S into H2 and S (H2S → H2 + S) is beneficial from both environmental and energy standpoints. Here we report that H2S can be splitted stoichiometrically into hydrogen and sulfur on CdSbased photocatalysts under visible light irradiation using ethanolamine as a H2S solvent and reaction media at room temperature. Raman spectra showed that the produced sulfur exi…

Effect of extra-framework gallium on the structure of iron species in Fe/ZSM-5
Abstract. A series of Fe/Ga-ZSM-5 catalysts with different Ga contents were prepared by solid-state ion exchange method. Ultraviolet and visible Raman spectroscopy, ultraviolet–visible diffuse reflectance spectroscopy, H2-temperature-programmed reduction, and N2O decomposition at 523 K were used to investigate the effect of extra-framework Ga on the nature of the Fe species in Fe/Ga-ZSM-5…

Enantioselective epoxidation of β-methylstyrene catalyzed by immobilized Mn(…
Abstract. Mesoporous silica-supported chiral Mn(salen) catalysts were prepared and evaluated in the heterogeneous asymmetric epoxidation of β-methylstyrene with NaClO as an oxidant. Homogeneous and immobilized Mn(salen) catalysts exhibit similar cis/trans ratios and ee values when trans-substrate is used but different cis/trans ratios and ee values when cis-substrate is used. The productio…

Direct immobilization of self-assembled polyoxometalate catalyst in layered d…
Abstract. We present a novel method for the fabrication of immobilized polyoxometalate catalysts that directly use a self-assembled polyoxometalate solution without isolation and purification. Specifically, self-assembled [WZn3(ZnW9O34)2]12− catalyst can be selectively immobilized into layered double hydroxides in the presence of undesired anions. The material thus obtained demonstrates h…
