Investigation of CO2 Electrolysis on Tin Foil by Electrochemical Impedance Spectroscopy

Autor: Norbert Wagner, Fabian Bienen, Kaspar Andreas Friedrich, Simon Geiger, Dennis Kopljar

Publikováno v: ACS Sustainable Chemistry & Engineering. 8:5192-5199

The conversion of CO2 on tin catalysts via electrolysis leads to valuable chemicals like CO and formate and can help to close the carbon cycle. In the current literature, catalysts for the electroc...
