Highly Active Mesoporous Nb-W Oxide Solid-Acid Catalyst

Pore‐ing acid: Mesoporous Nb–W oxides (Nb:W=3:7) are found to be a recyclable, highly active solid acid. They surpass ion‐exchange resins (Nafion 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 s...

Description
Summary:Pore‐ing acid: Mesoporous Nb–W oxides (Nb:W=3:7) are found to be a recyclable, highly active solid acid. They surpass ion‐exchange resins (Nafion 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.
