Coordination modulation induced and ultrasonic-assisted synthesis of size-controlled microporous metal–imidazolate framework crystals with enhanced adsorption performance

Abstract

Size-controlled metal–imidazolate framework crystals have been synthesized by combining the coordination modulation method and ultrasonic-assisted synthesis for the first time. Aqueous ammonia was used as the coordination modulator, and was found to be able to control the crystal size. The as-obtained crystals had improved adsorption properties compared with that of the bulk ones.
