Abstract

Interaction of SBA-15 with dilute ammonia and with dilute acetic acid was studied for aging times up to 1 month. The effect of interaction with the solutions on the SAXS pattern of SBA-15 was rather insignificant. Also the pore volume was not affected. In contrast the micropore volume and the specific surface area were substantially depressed as an effect of interaction with ammonia solution. Apparently ammonia locally destroys the walls between the pores of SBA-15, and the honeycomb structure is preserved elsewhere.

重新考察SBA-15的溶解度

研究了SBA-15与稀氨和稀乙酸的相互作用，老化时间长达1个月。溶液相互作用对SBA-15的SAXS模式影响不显著。孔隙体积也不受影响。相比之下，由于与氨溶液的相互作用，微孔体积和比表面积大大降低。显然，氨局部破坏了SBA-15气孔之间的壁，而蜂巢结构在其他地方被保留了下来。

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
