A　series　of　Ag2S/Ag2WO4　composite　microrods　with　different　Ag2S　contents　(10-50　wt%)　were　synthesized　via　a　facile　successive　precipitation　route.　The　texture　and　optical　properties　of　the　pure　Ag2S,　Ag2WO4,　and　Ag2S/Ag2WO4　composites　were　intensively　characterized　by　some　physicochemical　characterizations　like　N-2　physical　adsorption,　x-ray　diffraction,　scanning　electron　microscopy,　Fourier　transform　infrared　spectroscopy,　Ultraviolet-visible　spectroscopy,　x-ray　photoelectron　spectroscopy,　photoluminescence　spectroscopy,　and　photocurrent　measurements.　Under　visible　light　irradiation,　different　organic　dyes,　e.g.,　methylene　blue　and　methyl　orange　dye　were　applied　to　evaluate　the　photocatalytic　performances　by　their　photocatalytic　degradation　reactions.　The　Ag2S/Ag2WO4　composite　microrods　exhibited　superior　photocatalytic　activity　and　stability.　The　high　crystallinity　of　Ag2WO4　and　improved　texture　properties　of　Ag2S/Ag2WO4　resulted　in　their　enhanced　photocatalytic　property.　More　importantly,　the　Ag2S/Ag2WO4　heterojunctions　with　matching　electronic　band　structures　obviously　enhanced　the　separation　of　photo-generated　electrons　and　holes,　further　promoting　the　photocatalytic　reaction.
