Fig. 2: Morphological and structural characterization of pure graphenic carbon (g-C) and iron doped carbon (Fe/g-C).
From: Hybrid graphenic and iron oxide photocatalysts for the decomposition of synthetic chemicals

A–C SEM images of pure g-C, 32 wt% Fe/g-C, and a magnified region showing iron oxide crystallite grown on g-C surface, respectively (scale bars: A = 50 μm, B = 50 μm, C = 10 μm) (D) pXRD pattern. E FTIR spectra. F Raman spectra showing the D (1373 cm−1) and G (1589 cm−1) bands.
