摘　　要：纳米ＴｉＯ２在空心陶瓷微球上的固定化及光催化分解辛烷方佑龄＊赵文宽尹少华董庆华孙育斌（武汉大学化学系武汉４３００７２）（武汉工业大学分析测试中心武汉）关键词光催化分解，二氧化钛，空心陶瓷微球，固定化，辛烷１９９６－０８－２６收稿，１９９６－１１－１１...This paper reports a buoyant photocatalyst of nano sized TiO 2 loaded on the hollow ceramic microbeads by silane coupling. The morphology was observed by SEM, and the amount of TiO 2 bound to the beads was determined by spectrophotometry. Percentage moles of octane remaining in the solution phase after UV irradiation was analyzed by GC. It was observed that more than 90% of the octane photodecomposed in 60 min.
