Synthesis of all-silica hollow zeolites by selective demetallation

Abstract

We report a method to efficiently produce all-silica hollow zeolites by leaching their parent crystals in sodium aluminate and hydrochloric acid solutions successively. The extra-framework aluminum species resulted from the dissolution of sodium aluminate can protect the crystal rim from damaging, and are subsequently eliminated by acid wash.
