Preliminary study on controlling nanoconfined fluid behavior and modelling molecular thermodynamics: progress in development of high-specific surface area TiO₂

Due to prominent influence of interfacial properties and complicated coupling effect of diffusion and reaction mechanisms, molecular behaviors of nanoconfined fluid at interface are difficult to control which becomes a bottleneck of new technology development (e.g. membrane process, heterogeneous catalysis) in modern chemical industry. Confinement behavior of fluid molecules at interface was studied on chemically stable high-specific surface area titanium oxide on the basis of recent research progress of this group. The effects of diffusion and reaction mechanisms on interfacial fluid behaviors were assessed separately and controlling mechanism was explored. Further, preliminary study on proposed molecular thermodynamic model was performed by atomic force microscopy, which was able to correlate interfacial friction and molecular interaction, and to provide molecular parameters for the thermodynamic model.
