The electro-reforming of polymer plastic waste and CO2 has the merits for producing value-added chemicals alleviating environmental pollution. Herein, we report an electrocatalytic integrating strategy efficient valorization poly(ethylene terephthalate) (PET) to simultaneously produce formic acid at both anode cathode. NiCo2O4 electrocatalyst displays a high Faradaic efficiency 90% production, which indicates excellent selectivity PET hydrolysate oxidation. By coupling oxidation reaction with reduction reaction, assembled electrolyzer exhibits low cell voltage 1.55 V drive integrated two half-reactions. Furthermore, 155% can be achieved 1.90 V. This study suggests that could energy-efficient economically viable realize production chemicals.

Boosting Production of HCOOH from CO ₂ Electroreduction via Bi/CeO _x

Angewandte Chemie International Edition, Journal Year: 2021, Volume and Issue: 60(16), P. 8798 - 8802

Published: Jan. 29, 2021

Abstract Formic acid (HCOOH) is one of the most promising chemical fuels that can be produced through CO 2 electroreduction. However, catalysts for electroreduction to HCOOH in aqueous solution often suffer from low current density and limited production rate. Herein, we provide a bismuth/cerium oxide (Bi/CeO x ) catalyst, which exhibits not only high (149 mA cm −2 ), but also unprecedented rate (2600 μmol h −1 with Faradaic efficiency (FE, 92 %) generation media. Furthermore, Bi/CeO shows favorable stability over 34 h. We hope this work could offer an attractive strategy develop efficient superior activity desirable stability.
