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 silica support. The catalytic performance of the materials in ...
