Electrodeposited Films of Manganese–Bipyridine Complexes for Aqueous Electrochemical CO <sub>2</sub> Reduction
Bibliographic record
Abstract
The advancement and innovation of immobilized catalytic systems toward upscaling and improved stability for the efficient reduction of CO 2 have been a focal point in electrocatalysis research. Herein, the modification of carbon cloth electrodes is reported through the electropolymerization of a well-studied manganese bipyridine complex. A conjugated, polymeric network of manganese active sites is generated using diazonium ion chemistry, facilitating the conversion of CO 2 into highly valued C 1 products. Two variations of diamine manganese complexes are investigated by directing the film’s generated aryl radical polymer growth through surface attachment at either the 4,4′- or the 5,5′-substituent position of the respective bipyridine ligand. The functionalized electrodes were characterized via X-ray photoelectron spectroscopy (XPS) and various electrochemical measurements to determine the structure and electronic environment of the covalently anchored complexes. Electrolysis and cyclic voltammetry studies reveal the activity of the manganese devices in aqueous media for the production of syngas (CO and H 2 ) and formate (HCOO ¯ ), achieving turnover numbers (TON) of up to ∼8000 and electrolysis current densities of up to 10 mA/cm 2 .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
