摘要：

For the first time we report the room temperature fabrication of zeolitic imidazolate framework-7 microcrystals in aqueous solution exposure to ammonia atmosphere (derived from concentrated NH3). SEM images illustrated the effect of the ammonia atmosphere and synthesis time on the morphology of the product. On the basis of TG and XRD data, the as-made samples showed supreme thermal stability up to 400 degrees C. Other results revealed the significant chemical stability and microporous structure of the as synthesized ZIF-7. This method is promising for the efficacious, eco-friendly and large scale production of microporous ZIF-7 at low cost. (C) 2016 Elsevier B.V. All rights reserved.
