Autor: Siqi Zhao, Oliver Christensen, Zhaozong Sun, Hongqing Liang, Alexander Bagger, Kristian Torbensen, Pegah Nazari, Jeppe Vang Lauritsen, Steen Uttrup Pedersen, Jan Rossmeisl, Kim Daasbjerg
Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-11 (2023)
This study explores how the activity and selectivity of Cu electrodes for CO2 reduction can be tuned with organic films of different porosity and thickness. As a result, the films increase the local CO partial pressures and surface coverages.
