In many cases, the elemental bonding can be analyzed by EELS. For instance, the EEL spectra in Figure 2617 presents boron(B)-bonding to other elements in Co–Rux–B-O catalysts. For the xRu = 0 sample, the spectrum shows both contributions of B-Co bonds and B-O bonds. For 0.13≤ xRu ≤ 0.7, the B-K edge is dominated by the signals from B-O bonds together with a smaller contribution of B-M (metals) bonds. For the xRu = 1 sample, the B-K edge shows the B–Ru bonds and a wide peak attributed to B-O bonds.
