3D core–shell porous-structured Cu@Sn hybrid electrodes with unprecedented selective CO₂-into-formate electroreduction achieving 100%

Abstract

Cu-based catalysts are exceptionally advantageous for the electrochemical CO2 reduction reaction (CO2RR) to fuels and chemical products utilizing clean and renewable energy.

In Situ Reconstruction of a Hierarchical Sn‐Cu/SnOxCore/Shell Catalyst for High‐Performance CO2Electroreduction

“…Various non‐noble metals (for example, Sn, In, Bi, Cd, Zn, and Co) have been investigated as catalysts for selectively reducing CO 2 to C 1 products . Among these materials, Sn is the most attractive catalyst owing to its high activity and stability towards C 1 production . Besides, Cu‐based catalysts are also able to catalyze CO 2 RR to C 1 products .…”

Advances in Sn-Based Catalysts for Electrochemical CO2 Reduction

“…Until now, various Sn-based catalysts including single metals, alloys, oxides, sulfides, and their hybrids with carbon nanomaterials (e.g., carbon nanotubes and graphene) or metal oxide have been reported for the CO 2 ER. At present, the Faradaic efficiency (FE) of formate and CO can reach ~ 100% and over 90%, respectively [19][20][21]. Moreover, the catalyst types, sizes, morphologies, surface modification, and reaction conditions exhibit excellent effects on the performance of CO 2 ER.…”

Copper-indium bimetallic catalysts for the selective electrochemical reduction of carbon dioxide

“…Particularly, formate with a high hydrogen content is usually used as liquid fuel in fuel cells. Moreover, formate can also be directly used for fabric processing, tanning, textile printing, and silage storage, as well as metal surface treatment agents, rubber additives, and industrial solvents [5,[15][16][17][18]. Nonetheless, the CO2RR process is generally accompanied by high energy consumption owing to the sluggish kinetics and low selectivity toward formate production.…”
