In situ generated controllable Ag0-Ag+ sites for enhanced eletroreduction of CO2 to CO

In situ reduction of AgI to Ag nanoparticles (AgNPs) supported on C-doped boron nitride (AgI/BN-C) was developed for CO2 electroreduction to CO with a much enhanced faradaic efficiency (FE) of 99.5 % and a high current density of 56.3 mA cm−2. The enhanced performance is mainly attributed to the con...

Zusammenfassung:In situ reduction of AgI to Ag nanoparticles (AgNPs) supported on C-doped boron nitride (AgI/BN-C) was developed for CO2 electroreduction to CO with a much enhanced faradaic efficiency (FE) of 99.5 % and a high current density of 56.3 mA cm−2. The enhanced performance is mainly attributed to the controllable construction of Ag0-Ag+ sites, which effectively provides a large number of active sites, enhances the adsorption strength of the intermediate and accelerates the reaction kinetics.
