摘要：

Pore-ing acid: Mesoporous Nb-W oxides (Nb:W = 3:7) are found to be a recyclable, highly active solid acid. They surpass ionexchange resins (Naflon NR50 and Amberlyst-15) and zeolites (H-ZSM5 and H-Beta) in Friedel-Crafts alkylation and hydrolysis reactions (see picture). The high activity is due to strong acid sites and a mesoporous structure with a high surface area and easy reactant accessibility. (Figure Presented) © 2010 Wiley-VCH Verlag GmbH & Co. KGaA,.
