Abstract: As a new class 2D layered materials,Titanium oxide nanosheets have attracted great interest in the fields of catalysis,environment,energy and electronics.In this work,we provide an overview of the recent advance of titanium oxide nanosheets on their layered structure,synthetic methods,doping with metals or nonmetal,as well as their nanocomposites and applications in catalysis.Recent researches indicate that titanium oxide nanosheets with unique structure and special physical and chemical properties can achieve multiple functions by controlling their compositions and structures.Although titanium oxide nanosheets have a lot of advantages,they are still far from practical applications.Therefore it is demanded to explore new synthesis,doping and modification methods,and develop new composite materials.In addition,the reaction mechanism in the catalytic reaction process and the industrial application of titanium oxide nanosheets will be important research directions in the future.

Key words: titanium oxide nanosheets, layered titanate compounds, catalysis, synthesis, nanomaterials

摘要: 氧化钛纳米片材料为一种新兴的二维层状材料,在催化、环境、能源和电子领域引起人们广泛的关注。本文从催化研究的角度出发,综述了氧化钛纳米片材料的结构、制备方法、金属及非金属元素的掺杂、纳米片基复合材料和其在光催化、光电催化和热催化等方面的应用进展。分析表明氧化钛纳米片材料拥有特殊的形貌和特别的物理化学性质,通过控制材料的组成及结构变化,能够实现氧化钛纳米片材料的多种功能化。指出氧化钛纳米片材料虽然有着优良的性能,但是在实际应用中远不能满足要求。因此,优化合成和探索新形式的二氧化钛纳米片材料,对其表面进行改性及开发具有特殊功能纳米复合材料是解决其瓶颈的有效途径。探索催化反应过程中的反应机理,开发氧化钛纳米片基工业应用催化剂将是今后重要的研究方向。
