description <p dir="ltr">The electrochemical reduction of carbon dioxide (ERCO<sub>2</sub>) to chemical feedstock and fuels is a promising strategy for reducing excessive carbon dioxide emissions. There are various benefits of converting CO<sub>2</sub> to a single product and Pb is one of the active and efficienct catalyst for reducing CO<sub>2</sub> to HCOOH. The current work used the electro‐deposition method to produce manganese oxide (Mn<sub>3</sub>O<sub>4</sub>) (nano particle flakes) and highly active, low‐cost lead (Pb) catalysts with a variety of morphologies (Nano crystal Flakes, Nano wires, and Nano crystal sheets). For the first time, the Mn<sub>3</sub>O<sub>4</sub> catalyst was employed as the anode in the water oxidation process to produce protons, and the electrocatalytic effects of Mn3O4 and Pb on the ERCO<sub>2</sub> reaction were investigated. The influence of CO<sub>2</sub> reduction on catalyst loading is investigated and the lone product HCOOH is detected on the produced Pb catalysts. Using a systematic electrochemical study, the final product of the ERCO<sub>2</sub> reaction is identified and measured. The maximum Faradaic efficiency was measured on Pb (nano crystal flakes) at −1.003 V, yielding efficiency of 77.32 % (10 min) in 1 mg/cm<sup>2</sup> catalyst loading and 78.4 % on nano wires (10 min) at −1.003 V in 2 mg/cm<sup>2</sup> catalyst loading, respectively. More specifically, it is discovered that the reaction selectivity and efficiency of CO<sub>2</sub> electroreduction to HCOOH are highly influenced by the morphology and loading of the catalyst. These results provide an intimate understanding of water oxidation on Mn<sub>3</sub>O<sub>4</sub> and CO<sub>2</sub> electroreduction on Pb catalyst.</p><h2>Other Information</h2><p dir="ltr">Published in: ChemElectroChem<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1002/celc.202400527" target="_blank">https://dx.doi.org/10.1002/celc.202400527</a></p>
