Abstract: With excellent electrical conductivity, mechanical properties and large specific surface areas, graphene is a new material with great potentials. However, graphene is prone to stacking because of the intermolecular forces and π-π interaction between sheets. Constructing a three-dimensional hollow microsphere structure not only effectively prevents the agglomeration of graphene sheets, ensures a large specific surface area and excellent properties, but also has unique advantages of regular structures and adjustable sizes. This article describes the preparation methods of graphene hollow microspheres reported in recent years. It is mainly arranged and analyzed according to two major categories: template method and templateless method, and the template method is divided into two categories:hard template method and soft template method. Introductions and examples of various technologies applied in the preparation of graphene hollow microspheres are presented. The review concludes with the analyses and summaries of the hard template method, soft template method and templateless method respectively, as well as a discussion of future perspectives.

Key words: graphene, hollow microspheres, preparation method
