| | | | 研究了氧化锡为主体的N型气敏半导体作为气相色谱鉴测器的基本性能,其灵敏度与氢火焰鉴测器相当,一般物质可测至1~10 ppm,氢测到0.1ppm.试制成功了由此鉴测器构成的QSP-1型气敏色谱仪,经对稀有气体中微量氢杂质、电力变压器油气和某工厂乙烯车间大气污染等进行的分析,以及对石油勘探油气层位的测定等方面的应用研究,表明仪器灵敏度高、结构简单,可在某些实际中应用. | | 文摘来源 | | The photo-electrochemical properties of n-Type Polycrystalline TiO_2semiconductor electrodes are investigated. These samples are preparedby painting Ti(OC_4H_9)_4+C_4H_9OH solution, on Ti substrate with subse-quent heat-treatment in argor atomspher at 700℃ for one hour. X-ray diffraction data indicate that the investigated samples havethe rutile structure and point out that the Ti Substrate extra evidenteffect on the formation of the rutile structure.

The open circuit potential varies linearly with the logarithm of light intensity. The potentials of n-type semiconductor photoelectrodes shift to more positive values as the concentrations of oxidants in solutions increase, but they are almost unaffected by the concentrations of the reductants. Formula of photopotential was der... | | 光电化学电极的开路电位及其稳定性与电解质溶液的性质有关。光电极的开路电位与照射在电极上光的强度呈半对数关系。实验表明:对n-型半导体电极,随着溶液中氧化态浓度的增加光电位向正方向移动,而改变溶液中还原态的浓度对光电位影响不大。本文根据电极过程的基本原理解释了这些事实。在某些电解质溶液中还观察到光电极光生电位的滞后现象,文中用费米能级分裂的概念对出现这一现象的原因进行了讨论。 | | 文摘来源 | |   | | << 更多相关文摘 |
