Caption

Scanning electron microscope image (upper left), transmission electron microscope image (upper right), reduction characteristics (bottom left) and Faradic efficiency (bottom right) of Sn/rGO catalyst. </br> It can be seen that Sn nanoparticles of 10-50 nm are uniformly dispersed on the reduced graphene oxide sheet (upper left and upper right). Also, the absolute value of the current density under CO<sub>2</sub> flow is larger than that of the conventional catalyst (Sn) or Sn supported graphene oxide (Sn/GO), and the current increases from an initial electric potential of a lower absolute value. Thus, it can be seen that the overpotential is significantly reduced and that the current density is augmented. In addition, the Faradic efficiency of formate is very high using the Sn/rGO catalyst (bottom left and bottom right).
