To investigate the activation mechanism of manganese-based catalysts in CO2 reduction.
Utilized a three-component system including photosensitizer, electron donor, and manganese catalyst.
Applied time-resolved infrared spectroscopy to analyze the activation pathways.
Studied both monomer and dimer pathways of the catalysts.
Identified specific activation mechanisms for the manganese catalysts.
Demonstrated the role of electron donors in enhancing CO2 reduction efficiency.
Revealed distinct behavior between monomer and dimer catalyst pathways.
Abstract
The activation mechanism of Mn-based molecular catalysts is reported in a three-component system (photosensitizer, electron donor, catalyst), investigated by time-resolved infrared spectroscopy.
