A High Performance Cobalt-Doped ZnO Visible Light Photocatalyst and Its Photogenerated Charge Transfer Properties

引用

Nano Research 2011年第11期4卷 1144-1152页

作者： Yongchun Lu yanhong lin Dejun Wang lingling Wang Tengfeng Xie Tengfoi Jiang State Key Laboratory of Theoretical and Cornputational Chemistry State Key Laboratory of Supramolecular Structure and Materials College of Chemistry Jilin University Cheangchun 130012 China.

Highly photocatalytically active cobalt-doped ZnO （ZnO：Co） nanorods have been prepared by a facile hydrothermal process. X-ray diffraction, X-ray photoelectron spectroscopy, Raman scattering and UV-vis diffuse reflectance spectroscopy confirmed that the dopant ions substitute for some of the lattice zinc ions, and furthermore, that Co〉 and Co〉 ions coexist. The as-prepared ZnO：Co samples have an extended light absorption range compared with pure ZnO and showed highly efficient photocatalytic activity, only requiring 60 rain to decompose -93% of alizarin red dye under visible light irradiation （λ 〉 420 nm）, The photophysical mechanism of the visible photocatalytic activity was investigated with the help of surface photovoltage spectroscopy. The results indicated that a strong electronic interaction between the Co and ZnO was present, and that the incorporation of Co promoted the charge separation and enhanced the charge transfer ability and, at the same time, effectively inhibited the recombination of photogenerated charge carriers in ZnO, resulting in high visible light photocatalytic activity.

目的分析一例完全型雄激素不敏感综合征（complete androgen insensitivity syndrome，CAIS）患者及其家系成员雄激素受体（androgen receptor，AR）基因的潜在突变。方法提取患者及其家系成员的外周血基因组DNA和总RNA，应用PCR技术扩增X染色体上AR基因的7个外显子，对产物直接进行DNA测序，寻找突变位点；应用PCR-限制性片段长度多态性方法分析相应的基因组片段，进一步确证AR基因的突变位点；用逆转录PCR扩增AR基因，再次验证其突变位点。结果发现患者及其舅舅AR基因第7外显子的第2880个核苷酸G被A替换，引起错义突变，导致第840位密码子CGT突变为CAT，即精氨酸被组氨酸替代。该突变可能引起雄激素受体结合能力的变化，导致CAIS。患者母亲一条AR等位基因的第840位密码子亦存在CGT→CAT改变，另一条等位基因则未发现突变。结论AR基因第7外显子核苷酸序列2880位点碱基G引起的错义突变很可能是引起CAIS的原因。应用长链RT-PCR技术扩增AR基因可为CAIS的分子诊断提供新的方法。
