Abstract: | Different mesoporous nanoarchitectures of aluminum oxide are obtained by heat treatment of the products of a sol-gel process involving an ultrasonic treatment and using polyethylene amine, dodecyl sulfate, and dodecylamine as templates. The structure of the materials has been studied by the methods of low-temperature adsorption of nitrogen and diffraction of X-rays at small and large Bragg angles. Depending on the synthesis conditions, the structure of the pores in nanostructured aluminum oxide can change, with the formation of bottle-like, ordered cylindrical, wormhole-like cylindrical or slit pores. In this case, globular γ-Al2O3 particles serve as the primary structural units of the synthesized materials. |
