Electrolyte Induced Nanostructuring Greatly Promotes C C Coupling In Highly selective cu based catalysts for co 2 electroreduction were synthesized using electrolyte induced nanostructuring of a cu foil. in addition to enhanced surface roughness, the effect is associated with the formation and stability of cu species as revealed by operando spectroscopy. The molecular tuning induced by 4 mercaptopyridine over cu surface enhanced the adsorption of reaction intermediates in corr, improved the hydrogenation of *co, facilitated asymmetric *co *cho.
Publications 能源与环境小分子催化研究组 As c–c coupling is the most critical step toward c 2 production in co 2 rr 45,46, we developed the c–c coupling efficiency (η c–c coupling) to assess the probability of *co to embark on. The electrosynthesis of multicarbon (c 2 ) products such as ethanol (c 2 h 5 oh) and ethylene (c 2 h 4) from co 2 is highly attractive because of the versatility of these products in the chemical. 18 11 2019. electrolyte driven nanostructuring can be used to synthesise highly selective cu catalysts for co2 electrochemical reduction to valuable multicarbon products. operando spectroscopy measurements showed that, in addition to the effect of the enhanced roughness, subsurface oxygen, cu (i) species and adsorbed halides favour c c coupling. The molecular tuning induced by 4 mercaptopyridine over cu surface enhanced the adsorption of reaction intermediates in corr, improved the hydrogenation of *co, facilitated asymmetric *co *cho coupling and thus stimulated the co to acetate conversion. the surface modified cu 2 o nanocubes by 4 mercaptopyridine (cu 2 o pys) exhibited a high.

Specially, one can notice that the nitrogen doping of cu 2 s layer also triggered the self adjustment of water layer configuration in the initial 2*co state, which approached closely to the final *occo state c–c coupling, thus promoting the c–c coupling process (figure s2, supporting information). overall, our theoretical results suggested that the electronic and geometric asymmetry of the. Importantly, the enhancement was attributed to the spin antiparallel alignment of electrons to promote c–c coupling on asymmetric cu* cu sites; consequently, the optimal bias was reduced by ∼0.2 v under the magnetic field for c 2 products with faradaic efficiency >30% and selectivity >75%. our work uncovers a new paradigm for spin enhanced catalysis applicable to a broad range of chemical.
