New advanced approach of ultra-fast synthesis of ultrahigh-BET-surface area crystalline metal-organic-frameworks MOFs

摘要

The present investigations are introducing for the first time a facile new trend of applying industrial ultrahigh energy CO2-laser (doubly sources) with output of 1650 W as an energetic activator for hydrothermal technique. Fe(II)-2,3,7,8,12,13,17,18-Octa-ethyl-porphyrinato-coordinated polymeric MOFs were selected as model for application and it was successfully synthesized via high-energy intensive laser assisted in nine minutes only. The laser assisted Fe(II)-MOFs were carefully characterized via X-ray diffraction (XRD), scanning electron microscope (SEM) and three dimensional atomic force microscope (3D-AFM). Furthermore BET specific surface area of Fe(II)-MOFs was evaluated and gave promising results of 2743 m(2)/g which is better than some of common iron-MOFs mentioned in literatures.
