Brought to light : Ag 2 S–Ag hybrid nanotubes were synthesized by rapid microwave‐assisted sulfidation of Ag 2 CO 3 nanorods. The relative amounts of Ag 2 S and Ag in the hybrid structure can be controlled easily by varying the concentration of the sulfur precursor. The optimized Ag 2 S–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.
