(a) Plots of the total current density vs. potential for the SnO2/ZC catalysts prepared without annealing (as-prepared) and annealed under different temperatures and atmospheres (Ar 100°C, Ar/H2 100°C, and Ar/H2 300°C). Electrochemical data of commercial SnO2 NPs are also plotted for comparison. HCOO-, H2, and CO FEs of (b) the as-prepared sample and the annealed samples prepared under different conditions, namely, (c) Ar 100°C, (d) Ar/H2 100°C, and (e) Ar/H2 300°C. (f) Plot of the partial current density used for formate production as a function of the potential for various SnOx/ZC catalysts.
