Design of less than 1 nm Scale Spaces on SnO2 Nanoparticles for High‐Performance Electrochemical CO2 Reduction

Electrochemical carbon dioxide reduction reaction (CO2RR) is a promising approach to mitigate CO2 concentration and generate carbon feedstock. Recently, the (sub‐)nanometer design of catalyst structures has been revealed as an efficient means to control the reaction process through the local reaction environment. Herein, the synthesis of a novel tin oxide (SnOx) nanoparticle (NP) catalyst with highly controlled sub‐nanoscale interplanar gaps of widths
