W 4f electron binding energies in amorphous W-B-C systems

Amorphous WP‐Modified Hierarchical ZnIn2S4 Nanoflowers with Boosting Interfacial Charge Separation for Photocatalytic H2 Evolution

“…[ 47,54 ] It can be clearly seen that the peak area of W 4f 7/2 is smaller than that of W 4f 5/2 , which may be due to the local atomic environment of the W atom in amorphous WP affecting the peak type of W 4f. [ 55,56 ] The P 2p spectra of the two samples are depicted in Figure 5f, which exhibits two peaks of P 2p 3/2 and P 2p 1/2 discerned at the 129.55 and 129.81 eV while the single peak at 132.02 eV is the P–O bond. [ 57 ] The P 2p 3/2 and P 2p 1/2 peaks of the amorphous WP sample are derived from the W–P bond of metal phosphide, the result reveals that amorphous WP was successfully fabricated.…”

Nickel-Doped Decatungstate as a Robust Photocatalyst for Violet Light-Triggered Redox Coupling Conversion of Alcohol and Water to Aldehyde/Ketone and Hydrogen

“…As shown in Figure a, three energy peaks for the W 4f5/2, W 4f7/2, and W partner in TBADT appear at 37.64, 35.53, and 41.23 eV, respectively and their binding energies increase to some extent (about 0.14–0.44 eV) in the as-synthesized and especially postused 1%Ni-DT samples. The two O 1s energy peaks in TBADT are located at 531.96 and 530.59 eV (Figure b), which are assigned to the attributed to the WO and W–O–W bonds of the DT anion, , respectively. Compared to TBADT, the O 1s energy peak of WO bonds in the as-synthesized 1%Ni-DT increases by 0.27 eV, but its increase in the postused 1%Ni-DT is obviously reduced to 0.07 eV.…”
