Well-defined Fe–Cu diatomic sites for efficient catalysis of CO₂ electroreduction

Abstract

The diatomic catalysts (DACs) provide a new strategy for efficient catalysis of CO2 reduction reaction (CO2RR) owing to their maximum atomic utility and more flexible active sites. However, it is...

Mechanistic understanding and design of non-noble metal-based single-atom catalysts supported on two-dimensional materials for CO2 electroreduction

“…5c. 115 The tting results of EXAFS spectra (Fig. 5c) suggested the existence of Cu-Fe coordination.…”

Synergistically enhanced single-atomic site catalysts for clean energy conversion

“…114 Additionally, as another further expansion of the SAC series, DACs introduce synergistic sites to distribute electrons, which can break the linear relationship of adsorption energies of different reaction intermediates. For instance, an Fe-Cu diatomic site with a unique coordination structure (FeN 4 -CuN 3 ) was precisely controlled by He et al 115 As shown in 119 They studied 28 SAAs, and found that about half of them selectively favor the CO 2 RR over the competing HER (Fig. 11h).…”

Rational‐Designed Principles for Electrochemical and Photoelectrochemical Upgrading of CO2 to Value‐Added Chemicals

“…In addition, some works focused on combining Cu with other metals or metal oxides to break the scaling relations and contribute to highly selective CO formation at a decreased onset potential, which was caused by the balance between *COOH and *CO binding energies on the catalyst surface. Furthermore, CuAu, [ 68 ] CuPd, [ 69 ] CuZn, [ 70 ] CuCd, [ 71 ] CuFe, [ 72 ] In‐doped Cu@Cu 2 O, [ 73 ] and Cu/SnO x [ 74 ] had been studied to shift the main products to CO. Zn‐based materials have also been popular alternatives for ECR due to their abundant storage, low toxicity, and high CO selectivity. Woo's group reported a hierarchical hexagonal Zn catalyst, [ 75 ] which realized a highly efficient (FE CO,maximum = 95%) and stable performance (30 h) for CO production.…”
