Synthesis of Ag/AgCl/(x)Fe-ZX
Firstly, Ag2SO4 ammonia solution was prepared by dissolving
Ag2SO4 (10 mmol) in 2 mol L1 of the ammonia water (50 mL).
Then (x)Fe-ZX (1 g) was mixed with Ag2SO4 ammonia solution by
vigorous mechanical agitation as Ag2SO4/(x)Fe-ZX solution. NaCl
saturated aqueous solutions (50 mL) were also prepared in
advance. Subsequently, NaCl saturated solution was mixed with
Ag2SO4/(x)Fe-ZX solution by vigorous mechanical agitation to form
AgCl/(x)Fe-ZX solution. The AgCl/(x)Fe-ZX solution was illuminated
using 300W Xe arc lamp with the UV filter (Newport, USA) for
30 min. Then the product was washed with deionized water and
dried at room temperature. Finally, the Ag/AgCl/(x)Fe-ZX samples
were obtained. For comparison, pure Ag/AgCl was also prepared
by the same procedure without the addition of (x)Fe-ZX.
