TiO2/bamboo　charcoal　composites　were　prepared　by　sol-gel　technique　with　tetrabuty　tinanate　as　the　titanium　source,　and　60-mesh　bamboo　charcoal　as　the　support.　The　paper　studies　the　photocatalytic　degradation　ability　of　Rhodamine　B.　the　results　shows　that　the　degradation　effect　of　3-10mg/L　is　the　best　with　0.5-1.1g　TiO2　in　it.　The　best　pH　value　is　4.22.　The　photocatalytic　degradation　fits　in　with　the　first-order　kinetic　order.
