Correction to Structural Dynamics and Evolution of Bismuth Film Electrodes during Electrochemical Reduction of CO₂ in Imidazolium-Based Ionic Liquid Solutions

Abstract

I n row 18 of Table S1, under the "Parameter (units)" column, it read "Bismuth, crystalline layer roughness (Å)" but the correct parameter name is "SiC substrate surface roughness (Å)". The correct Table S1 is shown below.

Ni Hollow Fiber Encapsulated Bi@Zeolite for Efficient CO2 Electroreduction

“…Bi L 3 -edge XANES spectra demonstrate the near edge absorption energy of Bi@Zeolite closed to Bi powder, which shifted to lower photon energy compared to the oxygenated Bi 2 O 3 , implying a majority of Bi 0 valence state in the bulk Bi@Zeolite phase (Figure a). The Fourier transformed k 3 -weighted EXAFS curve of Bi@Zeolite (Figure b) shows distinct multi-Bi 0 peaks at 2.55 and 3.06 Å with a nominal coordination number of 3, which agrees well with the R 3̅ m structure according to the XRD results . A prepositive peak emerged at 1.32 Å suggesting the single scattering of oxygenic-type bismuth (Bi–O), which can be ascribed to the oxygen-susceptible feature on the surface of Bi-based materials. , The shorter Bi–O radical distance of Bi@Zeolite than those of Bi powder and Bi 2 O 3 elucidates the efficient confinement of the zeolitic matrix to Bi nanostructures, which is in line with the previous metal-based nanostructure effects. , To cross-validate the electronic states of Bi@Zeolite, X-ray photoelectron spectroscopy (XPS) analyses of Bi 4f and O 1s fine structure were investigated.…”
