High‐Current‐Density Acidic CO 2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnO x

Qiaoqi Guo, Bowen Jiang, Le Huang, Kunyu Jiang et autres

ABSTRACT Acidic CO 2 electrolysis to formic acid circumvents carbonate formation and enables direct product recovery, yet is hindered by severe competition between formate‐producing *OCHO and hydrogen‐producing *H intermediates. Here, we develop a hierarchical site‐solvation‐transport regulation strategy to direct this competition toward …

Efficient Acidic CO 2 Electrolysis with Suppressed Crossover in a Separator-Based Membrane Electrode Assembly

Min Liu, Yuke Li, Jianan Erick Huang, Xingyuan Chu et autres

Performing acidic electrochemical CO 2 reduction (CO 2 R) in flow cells suppresses CO 2 crossover but requires thick catholyte layers that impose large ohmic losses. Removing the catholyte, however, shifts selectivity toward H 2 due to excessive proton (H + ) …

Industrial amine blends enable efficient CO electrosynthesis in reactive capture

Siyu Sonia Sun, Yurou Celine Xiao, F. Li, J K Y Wu et autres

Higher post-capture bicarbonate concentrations improve CO FE but must be balanced against viscosity and conductivity. Screening the performance of binary and commercial amine blends, we find a CO energy efficiency (EE) of 31% at 50 mA cm −2 .

Efficient amino-acid-based reactive capture of CO2 via nickel molecular catalyst

Zunmin Guo, Feng Li, Yurou Celine Xiao, Sung‐Fu Hung et autres

Reactive capture integrates CO2 capture and electrochemical conversion into CO — a key building block in the synthesis of industrial chemicals and fuels — avoiding costly regeneration steps and improving efficiency. Amino acid salt solutions, which offer rapid CO2 capture, facile CO2 …

Crystalline‐Amorphous Heterostructures with Built‐In Electric Fields Enhance the Tandem Electroreduction of Nitrate to Ammonia

Yaling Chen, Xiang Liu, Yiran Li, Jianjun Li et autres

Abstract Electrochemical nitrate reduction to ammonia (NO 3 − RR) presents dual opportunities for sustainable ammonia synthesis and environmental nitrate remediation. However, the catalytic efficiency of the NO 3 − RR is hindered by the slow kinetics and substantial side reactions. Herein, …
