【摘要】 利用电化学阳极氧化法制备出了高度致密,有序的二氧化钛纳米管阵列(TiNT).通过光化学沉积方法在二氧化钛纳米管表面沉积了Ag金属颗粒,并用SEM进行了表征,Ag颗粒的半径在100~500 nm之间.通过对光化学沉积后的TiNT样品进行光电响应和光催化降解测试发现:紫外光照射下改性样品的光电响应能力和光催化降解能力都有不同程度的提高,但在可见光下仍不具备光电响应能力和催化降解能力.更多还原

【Abstract】 Dense and highly ordered titania nanotube was fabricated by anodic oxidation.SEM was used to characterize surface and structure of titania naotube.The diameter of Ag particles were between 100 to 500 nm.Photo-electrochemical and photo-decomposition experiments of Ag particle-covered titania nanotubes under UV and visible light were tested.Data indicated that performance of modified titania naotubes were enhanced under UV,but not under visible light.更多还原
