| 2. | The experiments of decompositing methylene blue with the films of different thickness show that the threshold of thickness on these films are 141nm , before which the rate of decomposition increases , and when the thicknesses is over 141nm , the rate of photodegradation no longer increases
通过不同厚度薄膜对亚甲基蓝的光催化降解试验发现,本试验得到的tio _ 2 : w非晶态薄膜厚度的阈值为141nm ,在此范围内,薄膜的光催化性能随膜厚的增加而增强。 |
