Abstract

Ceramic oxides nanofibers are promising materials as catalysts, electrodes and functional materials. In this report, a unique lamellar-like mesoporous structure was realized for the first time in a new system based on titania and alumina. The final structure was found to be highly dependent on the process conditions which are outlined herein. In view of the similar architecture we recently obtained with Fe-Al-O fibers, the pore formation mechanism we outline herein is general and is applicable to additional systems.

摘要

陶瓷氧化物纳米纤维作为催化剂、电极和功能材料是很有前景的材料。在本报告中，首次在基于二氧化钛和氧化铝的新体系中实现了独特的层状介孔结构。发现最终结构高度依赖于本文所述的工艺条件。鉴于我们最近用铁铝氧化物纤维获得了类似的结构，我们在此概述的孔形成机制是通用的，适用于其他体系。
