Fig. 4: BP-induced enhancement of CO2RR performance on Bismuthene.
From: Bismuthene for highly efficient carbon dioxide electroreduction reaction
a SEM image of the transect to show the compact catalyst layer of Bismuthene nanosheets on carbon paper electrode. b Partial current density for HCOO− (jHCOO-) versus potential on Bismuthene and Bismuthene@BP (with BP 3 wt.% optimally). c SEM image of the transect to show the noncompact catalyst layer of Bismuthene@BP on carbon paper electrode. The arrows in (a, c) indicate the thickness difference of the catalyst layers with the same mass loading, scale bars in (a, c): 1.0 μm. d ECSA measurement for both pure Bismuthene and Bismuthene@BP. All the error bars in (d) represent the standard error of the mean.
