当用能量大于其禁带宽度的光照射通有氧气的ＴｉＯ２悬浮液时，在ＴｉＯ２微粒表面会产生反应活性很高的空穴和Ｏ２－、Ｈ２Ｏ２等多种活性氧．在上一篇文章中［１］我们已报道了在通氧气和紫外光照的条件下，向ＴｉＯ２悬浮液中加入少量Ａｇ＋或Ｐｄ２＋，将会大幅度提高...
When the TiO2 suspension with oxygen is irradiated with light whose energy is greater than the forbidden band width, many reactive oxygen species such as O2-, H2O2 and the like are generated on the surface of the TiO2 particles. In the last article [1] we have reported that by adding a small amount of Ag + or Pd2 + to the TiO2 suspension under oxygen and UV light irradiation, we have dramatically increased ...
