Preparation of graphene plays an important role in theoretical and applied research of graphene. Chemical reduction of exfoliated graphite oxide （graphene oxide） appears to be one of the most important routes for graphene production available at present. In this paper, reduction methods of graphene oxide, such as using reducing agent reduction, thermal treatment reduction, electrochemical reduction, solvothermal reduction, catalytic reduction and microwave reduction are summarized, and the advantages and disadvantages are also analyzed. The research directions of the reduction methods of graphene oxide are discussed, such as changes in atomic structure after reduction and reduction mechanism, new reduction method and integration of two or more reduction methods, simultaneous reduction of graphene oxide and preparation of compounded graphene.
