Microwave-assisted synthesis of porous Ag2S-Ag hybrid nanotubes with high visible-light photocatalytic activity

Brought to light: Ag2S–Ag hybrid nanotubes were synthesized by rapid microwave-assisted sulfidation of Ag2CO3 nanorods. The relative amounts of Ag2S and Ag in the hybrid structure can be controlled easily by varying the concentration of the sulfur precursor. The optimized Ag2S–Ag hybrid structure ha...

Description
Summary:Brought to light: Ag2S–Ag hybrid nanotubes were synthesized by rapid microwave-assisted sulfidation of Ag2CO3 nanorods. The relative amounts of Ag2S and Ag in the hybrid structure can be controlled easily by varying the concentration of the sulfur precursor. The optimized Ag2S–Ag hybrid structure has superior photocatalytic activity (yellow) for both degradation of methyl orange (see graph) and reduction of aqueous CrVI under visible-light irradiation.
