Modulating Activity through Defect Engineering of Tin Oxides for Electrochemical CO₂ Reduction.

ABSTRACT: The large-scale application of electrochemical reduction of CO₂, as a viable strategy to mitigate the effects of anthropogenic climate change, is hindered by the lack of active and cost-effective electrocatalysts that can be generated in bulk. To this end, SnO₂ nanoparticles that are prepared using the industrially adopted flame spray pyrolysis (FSP) technique as active catalysts are reported for the conversion of CO₂ to formate (HCOO^-), exhibiting a FE_HCOO ^- of 85% with a current density of -23.7 mA cm^-2 at an applied potential of -1.1 V versus reversible hydrogen electrode. Through tuning of the flame synthesis conditions, the amount of oxygen hole center (OHC; Sn≡O●) is synthetically manipulated, which plays a
