The synthesised ZIF-62 particles were fully activated in the vacuum oven
at 150 oC for 24 hours before Ag adsorption to ensure
maximal adsorption of Ag+ into the ZIF-62 pores. The
activated particles were then lightly crushed and mixed using a small
pestle and mortar to reduce possible agglomeration during activation and
drying. The lightly ground ZIF-62 particles were then dispersed into a
0.05M methanol solution of AgNO3 and stirred at 300 rpm
using a magnetic stirrer for 1 hour. The resulting suspension was then
centrifuged at 9500 rpm for 15 minutes using Cence H1850 high-speed
centrifuge and dried at 70 oC for 5 hours before being
stored in a dark and cool condition. The Ag-doped ZIF-62 can be further
melted at a temperature ranging between 400 oC-450oC using a furnace with an Argon environment for 5
minutes to form the glassy/thermally treated version of these materials.
