(a), Fourier transform infrared analysis spectra (b) and XPS spectra of C element of graphene sheets (c) before and after irradiation (Black, no irradiation; Red, AO; Green, UV; and Blue, EL). Full size image Figure 1b shows the FTIR spectra of the samples before and after irradiation...
Our results validate the use of independent DFT predicted BE shifts for defect identification and constraining ambient pressure XPS observations for Me–Nxmoieties in pyrolyzed carbon based ORR electrocatalysts. This supports the understanding of such catalysts as vacancy-and-substitution defects in a gra...
