Abstract: The facile synthesis of zeolitic imidazolate frameworks(H-ZIF-67) under fully avoided solvent and a short reaction was achieved. The solid-phase transformation of mixed metal and organic ligand sources during the heat treatment process was a crucial mechanism of synthesis strategy. The synthesized materials were characterized by means of powder-XRD, SEM, TEM, TGA, FTIR, porosity, and N2 adsorption-desorption analyses. The results illustrate the characteristic properties compatibility with the commercial methods for the preparation of ZIF-67 have been reported. The single-step, truly solvent-free, non-post treatment, short-time synthesis, and safety system as ambient pressure, were an advantage of this developed method.

Key words: Zeolite imidazolate framework material, Solid phase transformation, Solvent-free synthesis, Heat treatment
