Figure 3. (IMAGE) Kanazawa University Caption Conceptual scheme of Sn/rGO electrochemical imaging with a scanning electrochemical cell microscope (upper left), characteristics of CO<sub>2</sub> reduction on the rGO surface, on the Sn surface, and at the interface between Sn and rGO (upper right), topography under electrochemical cell microscope (bottom left; 1, on the Sn surface; 2, at the interface between Sn and rGO; 3, on the rGO surface) and reduction current mapping (bottom right). This figure shows that CO<sub>2</sub> is efficiently reduced at the interface between Sn and rGO.
