摘要：
We report a citric acid-assisted solvothermal method to construct C@SnS@C sandwich nanosheets, which assemble into 3D porous microspheres. Citric acid plays a key role in both controlling the growth of the thin (5 nm) SnS nanosheets by absorption on the (100) SnS surface, and in the formation of an amorphous atomically thin carbon (ATC) layer (0.8 nm) on the surface of SnS nanocrystals through carbonization. The C@SnS@C sandwich nanosheets are used as precursors to form porous microsphere SnO
