[交流] 求助翻译一点点

各样品的紫外-可见吸收光谱见图4。样品有较强的紫外吸收能力,在波长大于410nm的可见光区,其吸收相对较弱,其吸收边位于410nm左右。与纯TiO2相比,样品Cd-TiO2 、N-TiO2和N,Cd-TiO2的光吸收增强,并发生一定程度的红移。N,Cd-TiO2的光吸收最强,其光响应范围已向可见光区拓展。各样品的吸收边波长和禁带宽度列于表2。由表2可以看出,与纯TiO2的禁带宽度相比,掺杂TiO2的禁带宽度均变窄,增大其对可见光的吸收,这也是增强可见光催化反应效果的原因。其中N,Cd -TiO2的禁带宽度最小,其光吸收最强。

These samples of UV - visible absorption spectra follow the Figure 4. Samples have strong UV absorption capacity, in the visible wavelength greater than 410nm, the absorption is relatively weak, its absorption edge at around 410nm. Compared with pure TiO2 ,sample Cd-TiO2, N-TiO2, and N, Cd-TiO2 light absorption increased, and caused a certain degree of red shift. N, Cd-TiO2  absorption is the strongest, the optical response range of the visible area has been expanded. The absorption edge wavelength of the samples and the band gap shown in Table 2. As can be seen from Table 2, with the band gap of pure TiO2 compared to doped-TiO2 band gap were narrowed, increasing its absorption of visible light, which is enhanced catalytic effect of visible light, causes. Where N, Cd-TiO2 band gap of the smallest, the strongest of its optical absorption.
