Solvents and Supporting Electrolytes in the Electrocatalytic Reduction of CO2

Autor: Maximilian König, Jan Vaes, Elias Klemm, Deepak Pant

Publikováno v: iScience, Vol 19, Iss , Pp 135-160 (2019)

Different electrolytes applied in the aqueous electrocatalytic CO2 reduction reaction (CO2RR) considerably influence the catalyst performance. Their concentration, species, buffer capacity, and pH value influence the local reaction conditions and imp

Ruthenium Complexes of Polyfluorocarbon Substituted Terpyridine and Mesoionic Carbene Ligands: An Interplay in CO 2 Reduction

Autor: Felix Stein, Maite Nößler, Arijit Singha Hazari, Lisa Böser, Robert Walter, Hang Liu, Elias Klemm, Biprajit Sarkar

Publikováno v: Chemistry A European Journal

In recent years terpyridines (tpy) and mesoionic carbenes (MIC) have been widely used in metal complexes. With the right combination with a metal center, both of these ligands are individually known to generate excellent catalysts for CO2reduction. I

Optimizing Reaction Conditions and Gas Diffusion Electrodes Applied in the CO2 Reduction Reaction to Formate to Reach Current Densities up to 1.8 A cm–2

Autor: Fabian Bienen, Dennis Kopljar, Elias Klemm, Maximilian Schmidt, Norbert Wagner, Armin Löwe

Publikováno v: ACS Sustainable Chemistry & Engineering. 9:4213-4223

Achieving high current densities in the electrochemical reduction of CO2 is one of the critical issues keeping this technology from commercialization. Although in the past few years, gas diffusion ...
