Fabrication of Ultrahigh-Loading Dual Copper Sites in Nitrogen-Doped Porous Carbons Boosting Electroreduction of CO to CH Under Neutral Conditions.

Synthesis of high-loading atomic-level dispersed catalysts for highly efficient electrochemical CO reduction reaction (eCORR) to ethylene (CH) in neutral electrolyte remain challenging tasks. To address common aggregation issues, a host-guest strategy is employed, by using a metal-azolate framework (MAF-4) with nanocages as the host and a dinuclear Cu(I) complex as the guest, to form precursors for pyrolysis into a series of nitrogen-doped porous carbons (NPCs) with varying loadings of dual copper sites, namely NPC-Cu-21 (21.2 wt%), NPC-Cu-11 (10.

Dicopper(I) Sites Confined in a Single Metal-Organic Layer Boosting the Electroreduction of CO to CH in a Neutral Electrolyte.

It is challenging and important to achieve high performance for an electrochemical CO reduction reaction (eCORR) to yield CH under neutral conditions. So far, most of the reported active sites for eCORR to yield CH are single metal sites; the performances are far below the commercial requirements. Herein, we reported a nanosheet metal-organic layer in single-layer, namely, [Cu(obpy)] (, Hobpy = 1-[2,2']bipyridinyl-6-one), possessing dicopper(I) sites for eCORR to yield CH in a neutral aqueous solution.

A Conductive Dinuclear Cuprous Complex Mimicking the Active Edge Site of the Copper(100)/(111) Plane for Selective Electroreduction of CO to CH at Industrial Current Density.

Inorganic solids are a kind of important catalysts, and their activities usually come from sparse active sites, which are structurally different from inactive bulk. Therefore, the rational optimization of activity depends on studying these active sites. Copper is a widely used catalyst and is expected to be a promising catalyst for the electroreduction of CO to CH.
