Rational design and facile synthesis of two-dimensional (2D) materials still remain a great challenge. Herein, a facile process was proposed to construct 2D porous hybrid nanosheets, with ultrathin antimony nanoplates (with a thickness of ca. 0.5 nm) being anchored on acetone-derived graphene-like carbon porous nanosheets, by an aldol reaction and subsequent carbothermal reduction method using acetone and antimony acetate as the starting raw materials. The novel structural and compositional characteristics afford the 2D porous hybrid nanosheets with impressive boosting electrochemical sodium storage properties in terms of excellent cycling stability, high reversible specific capacity, and superior rate performance. The present work would provide significant value for the development of both synthetic methodology of 2D materials and their application as electrode active materials for energy storage and conversion.
