项目摘要

1.Structural changes of solid-liquid and interfaces induced by chemical reactions were investigated using situ Raman and in situ XRD.Reversible changes in stage and stacking structure were observed on intercalation/deintercalation of lithium in carbon materials. FTIR/DRA results for NO and CO adsorbed on Co/Mo catalysts subjected to reduction pretreatments at several temperatures indicates that the Co species interacts with Mo species and caps the coordinately unsaturated sites of Mo species. The dynamic mechanism of metal deposition and onto surfaces was clarified by in situ STM and in situ IR spectroscopy.2.Intrinsic functions of organic molecules, inorganic molecules, and carbon materials were investigated by spectrophotometric methods to understand the dimensional functions of molecular assemblies in solution. The inorganic radicals generated by light irradiation on metal complexes preferred electron-transfer reactions in polar solvents. The partition properties of micelles were investigated to develop a novel trace analysis system of Pt. The cluster formation in supercritical carbon dioxide was also investigated.3.Layred oxide compounds which have advanced luminescence and mechanical properties were prepared by solid state reactions, spray-pyrolysis method, or coprecipitation in solution. The rare earth ion-activated compounds showed high luminescence intensities. Ceria-doped zirconia showed high fracture strength.4.The electron- and energy-transfer mechanisms in bilayr and monolayr membranes were investigated by electrochemical and spectroscopic methods. The electron-transfer phenomena was accounted for based on a tunneling mechanism. Chemical information in local membrane area was obtained by microelectrochemical measurements.
