摘　　要：氮化氧钽(TaON)是—种可见光驱动光催化剂,在本文中,我们首次利用阳极氧化铝作为模板成功地制备了TaON超长笔直纳米线材料。我们制备的TaON纳米线材料具有规整的单斜晶体结构,在可见光(λ>420nm)降解甲基蓝水溶液的测试中,该纳米线表现出了优异的光催化活性。Long-extending straight nanowires of TaON, which is known as one of the most efficient visible-light driven photocatalysts, were successfully synthesized by using anodie aluminum oxide （AAO） as a template and Ta（OC2H5）5 as the starting material. The as-prepared TaON nanowires had a well-crystallized monoclinic structure and exhibited much higher activity than TaON powder in photocatalytic degradation of methylene blue （MB） in an aqueous solution under visible-light （λ〉420 nm） illumination.
