摘      要：For some specific catalytic reaction, how to construct active sites on two dimensional materials is of great scientific significance. Dye-sensitized solar cells（DSCs） can be viewed as one representative photovoltaics because in which liquid electrolyte with triiodide/iodide（I;/I;） as redox couples are involved. In this study, amino-functionalized graphene（AFG） has been designed according to theoretically analyzing iodine reduction reaction（IRR） processes and rationally screening the volcanic plot. Then, such AFG has been successfully synthesized by a simple hydrothermal method and shows high electrocatalytic activity towards IRR when serving as counter electrode in DSCs. Finally, a high conversion efficiency of 7.39% by AFG-based DSCs was obtained, which is close to that using Pt as counter electrode.
