路易斯(Lewis)和怀特曼(Whitman)的双膜理论把 11、整个相际传质过程简单化为气、液两膜的分子扩散过程。按双膜理论,在臭氧从气相被吸收到液相的过程中。在气液两相的相界处各存在一层很薄的量滞流壮态的气膜,臭氧从气相主体穿过气膜向气液相界扩散。在界面处溶解并达到平衡,界面处溶解的臭氧继续穿过液膜向液相...

Gas-Phase Structure of the Bromonium Ion of 2-Methylpropene 1,9-Dithia and 1,9-diselena substituents in dibenzochalcogenophenes 1 are in close proximity within the van der Waals S-S and Se-Se contacts and hence have... M Klobukowski,RS Brown - 《J.org.chem》 被引量: 13发表: 1994...
Compare with S, Se, Te, the Au/Ag NCs protected by O are less due to the small radius and hard Lewis basicity of the O atom. However, the metal-chalcogen interfaces will induce diverse properties due to differences in O, S, Se and Te. Th... Y Sha,J Chai,H Chong,... - 《Che...
Ferroelectric materials possess distinctive photochemical properties associated with the internal dipole of the material, which stems from the non-centrosymmetric nature of their crystal structure [60]. These unique characteristics contribute to their enhanced performance in photocatalysis. Thus, being a ...
According to the reviewed literature, acidity sites in TiO2 depend on the migration of “bulk” -OHs to the surface since the determination of the Lewis acidity of TiO2 is made by measuring only the hydroxyl groups on the surface. Ti4+ ions are potential electron-charge acceptors, i.e., ...
摘要: Porous γ-Al2O3 generally possesses a nm-scale local structure.The tetragonal average structure contains a substantial fraction of "non-spinel" Al atoms.The concentration of "non-spinel" Al atoms correlates with surface properties.关键词:...
