A 20.0-g amount of silver nitrate (99.9+% pure, Alfa Products) was dissolved in 40 ml distilled water. This 50% silver nitrate solution was added slowly to 180 g Kieselgel60 silica gel (40-63 pm particle size, Merck reagent) and hand mixed during this addition. The silver nitrat~ ilica mixture was then placed in a plastic container and mixed for 0.5 h using a PTFE stirrer blade, a heavy duty glass stirrer shaft and a Talboy T-Line laboratory stirrer. The silver nitrate-silica mixture was then spread in a thin layer on stainless-steel trays and dried in an oven maintained at 105-120 C for 17 min to remove the water.
