摘要:

水热合成法制备质子化钛纳米管(TNTs)是一种操作简单、条件温和、适合规模化生产的方法,受到广泛关注,由此方法得到的钛纳米管具有开放的管道结构、比表面积大、稳定性高、离子交换等特点。本文简述了水热法制备TNTs的机理,分析了前体材料、水热反应条件、后处理方法等因素对水热法制备TNTs的影响规律,介绍了近年来TNTs作为载体、光催化剂、酸催化剂、吸附剂的应用研究现状。分析表明,通过调控水热条件及后处理方法可获得结构、性能各异的TNTs材料,并且利用离子交换、掺杂、有机表面修饰等多样化方法获得改性TNTs材料,进一步提升了TNTs材料在光催化、酸催化、吸附等方面的性能。最后指出,未来主要研究热点是提高水热法合成效率、优化化学改性策略,获得性能各异的TNTs材料。

Abstract:

The preparation of titanate nanotubes by hydrothermal method is regarded as a simple, convenient and mild technique, and is suitable for large-scale production, which had received a lot of attention. Titanate nanotubes prepared by this method have unique features, including open-ended structure, large specific surface area, good stability and ion-exchangeable ability. In this paper, the formation mechanism of TNTs was introduced briefly. The influence of various preparation conditions such as precursor materials, hydrothermal conditions, post-treatment on the structure of the TNTs were reviewed in detail. Recent advances in the applications of TNTs as supports, photocatalysts, acid catalysts, and adsorbents were also reviewed. TNTs materials with different structures and properties can be obtained by adjusting both hydrothermal conditions and post-treatment process. In order to improve the performance of TNTs, the modified TNTs materials can be obtained by doping, ion exchange method, surface modification and other methods. Improving the efficiency of hydrothermal synthesis, optimizing chemical modification strategies and obtaining TNTs with different properties were the main development trends in the future.

Key words: titanate nanotubes, hydrothermal method, support, catalyst, acid catalysis, adsorbents
