石墨烯(graphene)是近年被发现和合成的一种新型二维平面碳质纳米材料。由于其新奇的物理和化学性质,石墨烯已经成为备受瞩目的科学新星,是纳米材料领域的一大研究热点。在石墨烯的研究中,基于石墨烯的无机纳米复合材料是石墨烯迈向实际应用的一个重要方向。本文在简要介绍石墨烯的结构、性质和制备方法的基础上,重点就近年来以石墨烯为基体的无机物(主要包括金属和半导体)纳米复合材料的合成和应用作一述评,并对石墨烯基无机纳米复合材料的研究和发展方向做了展望。

In past few years,we have witnessed the discovery and synthesis of graphene——a kind of ideal two-dimensional flat carbon nanomaterials.Owing to its novel and unique physical and chemical properties,graphene has been attracting more and more attention from scientific community and nowadays has become a sparkling rising star on the horizon of nanomaterials science.The graphene-based inorganic nanocomposites,derived from the decoration of graphene sheets with inorganic nanoparticles,are emerging as a new class of materials that hold promise for many applications.So far,numerous inorganic nanocomposites based on graphene have been successfully synthesized and show desirable combinations of these properties that are not found in the individual components.Herein,we briefly introduce the structure,properties and preparation methods of graphene,and then highlight the advance in the synthesis of inorganic nanomaterials /graphene composites,especially focusing on the metal /graphene and semiconductor /graphene nanocomposites.The potential applications of these nanocomposites are also discussed.These results underscore the exciting opportunities of developing next-generation graphene-based inorganic nanocomposites.
