ZIF-62(Zn) mel�ng was conducted in accordance with our previous report . Crystals were manually ground and the resul�ng powder was placed between two sheets of silica glass (microscope slides). The glass sheet -ZIF-62(Zn) -sandwich was fixed using two metal clamps, and heated slowly to 450 °C in nitrogen atmosphere, held at this temperature for 5 min, and cooled back to room temperature. The obtained agZIF-62 was finally removed from the silica sheets and stored for further use.
