Probing the Catalytically Active Region in a Nanoporous Gold Gas Diffusion Electrode for Highly Selective Carbon Dioxide Reduction

Aidan Q. Fenwick et al.

Summary: The study presents the use of a nanoporous gold catalyst for CO2 reduction in a gas diffusion electrode and investigates the role of wetting in electrochemical performance. The findings show high Faradaic efficiencies and maximum partial current density for CO. The wetting characteristics of the nanoporous GDE are discussed for improving catalyst performance and designing enhanced GDE architectures.

A Facile Strategy to Obtain Low-Cost and High-Performance Gold-Based Catalysts from Artificial Electronic Waste by [Zr48Ni6] Nano-Cages in MOFs for CO2 Electroreduction to CO

Zi-Hao Zhu et al.

Summary: In this study, a framework 1 composed of [Zr48Ni6] nano-cages was successfully prepared, showing high BET surface area and solvent/pH stability. This framework can selectively extract AuCl4- from electronic waste and be transformed into low-cost Au nanoparticle@1-x catalysts with tunable Au NPs sizes. The Au NPs in the framework exhibited excellent catalytic activity for CO2 reduction reaction and maintained high activity for a long time.
