High surface area tin oxide nanocrystals
prepared by a facile hydrothermal
method are evaluated as electrocatalysts toward CO<sub>2</sub> reduction
to formate. At these novel nanostructured tin catalysts, CO<sub>2</sub> reduction occurs selectively to formate at overpotentials as low
as ∼340 mV. In aqueous NaHCO<sub>3</sub> solutions, maximum
Faradaic efficiencies for formate production of >93% have been
reached
with high stability and current densities of >10 mA/cm<sup>2</sup> on graphene supports. The notable reactivity toward CO<sub>2</sub> reduction achieved here may arise from a compromise between the
strength of the interaction between CO<sub>2</sub><sup>•–</sup> and the nanoscale tin surface and subsequent kinetic activation
toward protonation and further reduction.
