低维无机功能材料的氢化调控研究

低维无机功能材料电学行为的调控主要依赖于本征异质原子掺杂，但是该方法在性质调控的同时，由于异质原子的嵌入常导致原有晶体结构对称性发生改变，产生变形扭曲甚至破坏．目前，基于清晰结构调控无机材料功能性依然是极具挑战性的难题．氢作为一种小半径轻原子，对低维无机功能材料的修饰或嵌入为调控无极功能材料物性带来了新思路，特别是通过氢的嵌入可以在结构不发生大变化的前提下调制材料载流子浓度并提升导电率，这已逐渐成为低维无机材料电学行为调控的重要途径．本文概述了近年来发展的系列氢化调控方法，以及通过对电子结构调制实现对电学行为的调控，并基于此广泛应用于能源领域、电子器件及催化等方面．

Hydrogenation and modulation of the low dimensional inorganic functional materials

The modulation of the intrinsic properties of the low dimensional functional materials is mainly relied on the heteroatom doping. However, the distortion and even destruction of the pristine structure is inevitable due to the crystal symmetry changes caused by the embedded heterogeneous atoms. And it is still challenging to modulate the functionality of inorganic materials upon the pristine stable structure. The incorporation of hydrogen, which is the lightest atom, can bring about the fine modulated intrinsic properties within the pristine stable structure, such as higher carrier concentration as well as high conductivity, paving the new way for the regulation of the low dimensional inorganic materials. We put forward the effective hydrogenation strategies and its modulation effect for the pristine electronic structure, which makes it possible for the wide application of function materials in energy, electronic devices and catalysis.
