XPS as a probe for the bonding nature in metal acetates

Abstract

Metal carboxylates are an extensive family of coordination compounds of growing importance in Materials Science; hence, there is a need for improving the characterization methods for these complexes, especially at...

Decomposition of methanol-d4 on Rh nanoclusters supported by thin-film Al2O3/NiAl(100) under near-ambient-pressure conditions

“…3c and d, and was assigned to a -COO* structure, such as carboxyl group (-COOD) or a carboxylate ion (-COO À ), on Al 2 O 3 /NiAl(100), since these species typically yield C 1s lines near 290.0 eV. [57][58][59][60][61][62] Their formation has been discussed in earlier works. 33 To reveal how methanol-d 4 decomposition altered with the cluster sizes under NAP conditions, we plotted the production of CO m * and C* from the decomposed methanol-d 4 per surface Rh site, as a function of the CD 3 OD pressure and cluster size (Fig.…”

“…3c and d, and was assigned to a –COO* structure, such as carboxyl group (–COOD) or a carboxylate ion (–COO − ), on Al 2 O 3 /NiAl(100), since these species typically yield C 1s lines near 290.0 eV. 57–62 Their formation has been discussed in earlier works. 33…”

“…The involvement of H 2 O* was evidenced by the C 1s line at 291.0 eV (Fig. 3), assigned to a –COO* structure on Al 2 O 3 /NiAl(100) 57–62 arising from the interaction of CD 2 O* with OH* (OD*), 33 with the OH* coming from the dissociation of H 2 O*. The energies of H 2 O* dissociation on these Rh surfaces were first examined.…”

Creating Conjugated C−C Bonds between Commercial Carbon Electrode and Molecular Catalyst for Oxygen Reduction to Hydrogen Peroxide

“…Here, three peaks are fitted for the amide (533.1 eV), the acetate (531.8 eV) and the methanol/Co−O (530.6 eV) (Figure 2c). [40] At first glance, Vulcan‐N 4 −Co still has the acetate peak. However, oxidized carbon moieties from the Vulcan obscure the O 1s region, having a broad range of different signals (broad peaks at 533.8 and 531.9 eV) [41] .…”

Anchoring Ce-modified Ni(OH)2nanoparticles on Ni-MOF nanosheets to enhances the oxygen evolution performance

“…S3b †) of C 1s is divided into three peaks at 288.1°, 284.8°, and 285.8°, corresponding to O-CvO, CvC, and C-O, respectively. 36,37 The Ce 3d spectrum (Fig. 3b) of Ce-m-Ni(OH) 2 @Ni-MOF can be deconvoluted to two sets of Ce 3d 3/2 (V, V1, V2) and Ce 3d 5/2 (U, U1, U2, U3, U4) peaks, in which the peaks of V1, U and U2 can be assigned to two Ce 3+ , and the peaks of V, V2, U1, U3, and U4 represent Ce 4+ .…”
