Densely packed, ultra-small SnO nanoparticles for enhanced activity and selectivity in electrochemical CO2 reduction

Jun Gu, Florent Héroguel, Xile Hu, Jeremy Luterbacher
Controlling the selectivity in electrochemical CO2 reduction is an unsolved challenge. While tin (Sn) has emerged as a promising non-precious catalyst for CO2 electroreduction, most Sn-based catalysts produce formate as the major product, which is less desirable than CO in terms of separation and further use. Here we report the synthesis and assembly of carbon black supported 2.6 nm tin monoxide (SnO) nanoparticles and their application in CO2 reduction. Remarkably high selectivity and partial current densities for CO formation were obtained using these SnO nanoparticles compared to other Sn catalysts. The high activity is attributed to the ultra-small size of the nanoparticles, while the high selectivity is attributed to a local pH effect arisen from the dense packing of nanoparticles in the conductive carbon black matrix.
