摘要：

Alumina-supported niobium oxide promotes Friedel-Crafts reaction of benzyl alcohol and anisole effectively. The optimized condition of the catalyst was 16 wt% as Nb2O5 and calcination temperature of 1173 K. The catalyst exhibits the Bronsted acidity despite calcination at such high temperatures.
