Abstract
The creation of a selective and efficient catalyst for the multi-electron reduction of carbon dioxide (CO₂) into valuable chemicals or renewable fuels is a crucial research area. As the use of non-renewable fossil fuels and the associated greenhouse gas emissions, predominantly CO₂, continue to rise, the need for renewable and sustainable approaches to energy increases. To address both the need for clean energy and to reduce the accumulation of CO₂ in the atmosphere, this work will investigate the synthesis and catalytic activity of Earth-abundant transition metal-based complexes supported by a pentadentate ligand. The macrocyclic ligand 7-methyl-4,7,10-triaza-1,2(2,6)-dipyridinacycloundecaphane was successfully synthesized and metalated with cobalt and nickel. To understand the catalytic abilities of these complexes for CO₂ conversion, both the electrochemical and photochemical performance of the synthesized complexes was investigated. The experimental results provide promising evidence of the two macrocyclic complexes’ capabilities to selectively reduce CO₂ into value-added products.
