Qing SunJingwei LiuYuchuan FuJianyi Shen

Abstract. Mesoporous VOx–TiO2 with high surface areas were prepared using the procedure of evaporationinduced self-assembly combined with ammonia posttreatment. The samples were characterized by Xray diffraction (XRD), laser Raman spectroscopy (LRS), transmission electron microscopy (TEM), N2 adsorption, temperature-programmed reduction (H2-TPR), microcalorimetry for the adsorption of NH3, …

Abstract Oxidative bromination of methane, mediated by HBr/H2O (solution), provides an original route for the production of oxygenates and gasoline directly from natural gas. However, the reported catalysts for this reaction all involved noble metals. From the consideration of replacing noble metal catalysts with cheaper oxides, various silica-supported oxide catalysts were surveyed. It was…

Abstract A tethered ligand-modified Rh/SiO2 catalyst was developed for hydroformylation with high stability. The catalyst was prepared by fastening both organic ligand and metal directly on the surface of support to avoid leaching, while at the same time the active species were formed in situ by coordination of the flexible ligand to the metal on the surface of SiO2. The immobilization of l…
