摘要：

We report two successful synthesis techniques resulted in single-phase Zn-ZIF-65 with a high specific surface area. The solvothermal method allowed to obtain large well-shaped crystals used for single-crystal XRD. We report a new MW assisted technique, which leads to a fast formation of ZIF-65 with hierarchical pore system; obtained samples contained both micro- and mesopores. Presence of micro- and mesopores was confirmed by high-resolution TEM images and analysis of nitrogen adsorption isotherm. The presence of mesopores in the micropore system is desirable for such applications as catalysis and gas storage. These additional pores lead to higher hydrogen capacity of ZIF-65 obtained using MW assisted technique.
