Recent Trends, Benchmarking, and Challenges of Electrochemical Reduction of CO2 by Molecular Catalysts

“…[122] Based on pH testing, they proposed that PYD combines with a hydrogen cation and is then reduced to the PYD radical, which upon reacting with CO 2 forms intermediate products like formic acid (a trace product in the above CPE) eventually leading up to methanol similar to the Py/Pt homogenous system created by Bocarsly and co-workers. [123] Spectroscopic analysis confirmed the entrapment of PYD inside the Cu-Pt alloy (confirmed by XRD) cage formed by aggregation of the metals around the PYD molecules.

“…In addition, the intrinsic conductivity of the pure MOFs electrocatalyst prominently affects the electrocatalytic activity, mass transport, and charge propagation during the reaction.
