Abstract

Supermicroporous (1.5–2.5 nm pore diameter) niobium oxide is synthesized using a nonionic block copolymer as a structural directing reagent, which is removed by water washing after aging. The oxide contains water in the bulk material in the form of a water-rich niobium oxide. The supermicroporous niobium oxide is applicable for various acid-catalyzed reactions.
