摘要：

In　recent　times,　silver　(Ag)　based　semiconductors　have　been　gained　a　lot　of　attention　as　photocatalysts　for　industrial　waste-water　treatment　owing　to　their　strong　visible-light　absorbing　capability　and　small　bandgap　energy.　Therefore,　herein,　we　have　designed　and　utilized　a　one-pot　hydrothermal　approach　to　the　synthesis　of　nano-sized　AgBr　covered　potato-like　Ag2MoO4　composite　photocatalysts　for　the　elimination　of　organic　wastes　from　the　aquatic　environment.　To　achieve　a　high-performance　photocatalyst,　a　sequence　of　AgBr/Ag2MoO4　composites　were　acquired　with　varying　CTAB　from　1　to　4 mmol.　Furthermore,　the　photocatalytic　activity　of　these　photocatalysts　was　confirmed　from　decomposing　of　Rhodamine　B　(RhB)　dye　via　visible-light　elucidation.　It　can　be　noticed　that　AgBr/Ag2MoO4　composites　exhibited　significantly　increased　photocatalytic　behaviour　as　compared　with　pure　AgBr　and　Ag2MoO4.　Surprisingly,　the　AgBr/Ag2MoO4　composite　obtained　from　2 mmol　CTAB　was　eliminated　the　entire　RhB　dye　with　25 min.　Also,　the　recycling　experiment　indicates　the　AgBr/Ag2MoO4　composite　has　an　excellent　photo-stability.　Accordingly,　the　as-acquired　AgBr/Ag2MoO4　composite　would　be　a　suitable　photocatalytic　material　for　industrial　waste-water　purification.
