Fig. 4: Mechanism exploration for CO-to-oxygenates electroconversion over Cu-Ag.
From: High yield electrosynthesis of oxygenates from CO using a relay Cu-Ag co-catalyst system
a Operando XANES spectra of Cu in Cu/30Ag during the CORR. b The performance comparison of no interface (physically mixed Ag/Cu), rich interface (the sample synthesized by fast reduction in water without ammonia) and partial interface (Cu/30Ag). Error bars correspond to the Standard Deviation (SD) of three independent measurements. c ECSA-normalized partial current density of oxygenates. RF was used to replace ECSA for calculation due to a positive relationship between ECSA and RF19. Error bars correspond to the Standard Deviation (SD) of three independent measurements. d Online DEMS measurements of Cu, Ag, Cu/30Ag and the physical mixture during the CORR. e In situ flow-cell-type Raman spectra of Cu, Ag, Cu/30Ag and the physical mixture during the CORR.
