Abstract. For the first time, the high-activity, single-site mesoporous WO3-MCF materials were synthesized and characterized by N2 sorption, TEM, UV–vis DRS, UV-Raman, and XPS. It was found that the dispersion and nature of the tungsten species depend strongly on the tungsten oxide content and the support characteristic. The novel catalyst remains a highly ordered mesostructure of the sili…
Abstract. Ni–B nanospheres were synthesized through chemical reduction of nickel ions with borohydride in an emulsion system comprised of cyclohexylamine, polyethylene glycol, and water. With the characterization of X-ray diffraction, selective area electronic diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy, the resulting hollow Ni–B nanospheres were …
Abstract. Fe-doped titanium dioxide (TiO2) microspheres with special core–shell structure were prepared by a simple hydro-alcohol thermal method. The morphology and microstructural characteristics of Fe-doped titaniamicrospheres with different Fe3+ doping concentrations were characterized bymeans of BET, TEM, SEM, XPS, UV–vis DRS, PLS and XRD. The Fe3+ doped TiO2 samples showed the best…
