摘要：
Brought to light: Ag 2S-Ag hybrid nanotubes were synthesized by rapid microwave-assisted sulfidation of Ag 2CO 3 nanorods. The relative amounts of Ag 2S and Ag in the hybrid structure can be controlled easily by varying the concentration of the sulfur precursor. The optimized Ag 2S-Ag hybrid structure has superior photocatalytic activity (yellow) for both degradation of methyl orange (see graph) and reduction of aqueous Cr VI under visible-light irradiation.
