(a) C1s XPS spectra (symbols) of p-chGNRs “as grown” (top), after hydrogenation (middle) and after subsequent annealing (bottom), along with the fit (solid curve) and its associated components (coloured peaks). The data reveal the successful hydrogenation and its reversibility. (b) C1s XPS spectra (symbols) of k-chGNRs “as grown” (top), after hydrogenation (middle) and after subsequent annealing (bottom), along with the fit (solid curve) and its associated components (coloured peaks). The data reveal the gradual deoxidation upon hydrogenation and the subsequent annealing. Dashed lines act as a guide to the eye to compare the maxima on each of the spectra. Details about the fitting procedure are given in the methods section.
