1高等地质教育发展的新阶段与新任务——科学发展观与地学教育改革显示文摘高等地学教育面临新的形势和任务,地学教育进入了新的发展阶段。发展地学教育,要进一步实现好大学的三项基本功能,以科学发展观统领地学教育工作全局。赵鹏大 2005中国地质教育2005,14,4:21
2Electrochemical preparation and abnormal infrared effects of nanostructured Ni thin film显示文摘Nanometer-scale thin film of Ni supported on glassy carbon (nm-Ni/GC) was prepared by electrochemical deposition through cyclic voltammetry (CV). The properties of nm-Ni/GC were studied by electrochemical in situ FTIR reflection spectroscopy using CO adsorption as probe reaction. It has revealed that the nm-Ni/GC exhibits almormal infrared effects (AIREs). The study has extended the inves-tigation of the AIREs that we have discovered initially on nanostructured film materials of platinum group metals and alloys to nanostructured film materials of iron group metals.WANGHanchun ZHOUZhiyou TANGWei YANJiawei SUNShigang 2004Chinese Science Bulletin2004,49,5:3
3CO adsorption on electrode of Pt nanoparticles investigated by cyclic voltammetry and in situ FTIR spectroscopy显示文摘Pt nanoparticles were prepared by the chemical reduction method. The average diameter of Pt nanoparticles was determined to be 2.5 nm by TEM. The electrochemical properties of Pt nanoparticles were studied by cyclic volt-ammetry. In comparison with massive Pt, the oxidation cur-rent peak of CO adsorbed on Pt nanoparticles is broader. Twin adsorbates of CO on Pt nanoparticles were determined by in situ FTIRS for the first time. It has revealed that the linear and twin-bonded CO can be converted into bridge-bonded CO with the variation of electrode potential. A series of special properties of Pt nanoparticles, such as enhanced IR absorption of CO adsorbates, were also ob-served.CHEWWei JIANGYanxia2003Chinese Science Bulletin2003,48,2:0
4钴铂合金薄膜的循环伏安电沉积及其异常红外性能研究显示文摘运用循环伏安电沉积在玻碳基底上制得纳米结构钴铂合金薄膜,扫描电子显微镜和X-射线能量散射谱研究表明,钴铂薄膜主要由平均粒经为139 nm的纳米粒子组成,钴和铂的原子比为3∶5.以CO为探针分子,电化学原位FTIR反射光谱研究发现钴铂薄膜具有异常红外效应.吸附态CO发生异常红外吸收,谱峰比本体钴和铂分别增强了34和43倍.陈青松 郭国聪 孙世刚 2014电化学2014,20,5:0
