Tandem Catalysis
In article number 2214992, Andrew Barnabas Wong, Chunnian He, and co‐workers illustrate a design principle to improve the performance of tandem electrocatalysts for converting CO2 to C2+ products (ethylene and ethanol) by managing diffusion of the key intermediate, CO, within a 3D model system. This model system consists of Ag nanoparticles within a Cu nanoneedle array to restrict...
Tandem catalysis presents a promising strategy to improve the selectivity toward multicarbon products in the electrocatalytic carbon dioxide reduction reaction (CO2RR). For CO2RR, CO is a critical intermediate for producing multicarbon products. However, the management of CO localization and CO diffusion remains underexplored despite its critical role. Herein, a 3D tandem catalyst electrode with silver...
